Best Pre-Workout for Muscle Growth
Pre-workout supplements may be your secret weapon for monopolizing your gains before you even touch a barbell. It might help with your muscle growth goals if it’s stacked with the right ingredients. This pick contains massive doses of some potentially muscle-building ingredients, like beta-alanine and citrulline, along with modest doses of others.
Transparent Labs BULK
BULK is a pre-workout with 13 active ingredients coupled with B vitamins for energy and electrolytes for hydration. One of the important ingredients for muscle growth is the 4,000mg dose of beta-alanine that may help increase muscular endurance and delay fatigue, allowing you to go harder for longer in the gym. (1) On top of that, you’ll find ingredients to potentially support blood flow like citrulline (8,000mg) and betaine (2,500mg). The citrulline dose may help you recover more quickly and reduce post-workout soreness to get back after it in the gym faster. (2)

BULK also has alpha-GPC dosed at 300mg, 200mg of theanine, and 1,300mg of taurine in order to potentially improve your focus. While this isn’t the cheapest pre-workout on the market, it also isn’t absurdly expensive — especially if you consider the solid formula. You can pick up a 30-serving container for about $49.99 or around $1.67 per serving in a variety of 11 different flavors.

Best Protein Powder For Muscle Growth
A lot of protein powder on the market contains fillers, artificial sweeteners, and ingredients that don’t do much to help you maximize your muscle growth. This company created a whey isolate protein that prioritizes protein and leaves the artificial junk out, allowing the best opportunity to help with your gains.
Transparent Labs Whey Protein Isolate
Transparent Labs Whey Protein Isolate powder packs 28 grams of protein per serving, making it one of the higher protein content powders on the market per serving. Being a whey isolate also means it’s lower in carbohydrates and fats than a whey concentrate. This formula exclusively uses 100 percent grass-fed, hormone-free cows to provide its whey, and it’s free of any artificial sweeteners, food dyes, gluten, and preservatives.




Transparent Labs Whey Protein Isolate









With 8 different flavors and 28 grams of whey protein from hormone-free, grass-fed cows, Transparent Labs Whey Protein Isolate is an excellent way to hit your protein macros.







Transparent Labs’ whey isolate comes in eight delicious flavors — Oatmeal Chocolate Chip Cookie, Chocolate Peanut Butter, Milk Chocolate, Cinnamon French Toast, French Vanilla, Strawberry, Mocha, and Vanilla Peanut Butter. All eight flavors are great on their own or the perfect addition to your daily protein shake. Though this product is a little pricey at $2.00 per serving, we think this is a solid protein powder for muscle growth optimization.
Transparent Labs Grass-Fed Whey Isolate

If you’re on a budget, you’ll find cheaper options on the market — especially if you aren’t attached to an isolate formula.

Not all protein supplements are made equal, and this one stands above the rest due to its high protein content, all-natural ingredients, and eight delicious flavors.

Best Post-Workout for Muscle Growth
Post-workout fuel is an important part of the muscle recovery process and might be the ingredient that allows you to recover faster and get back into the gym for more intense lifts. The pea protein and electrolytes in this formula can potentially assist in recovery and hydration.
Swolverine POST
This vegan formula is the best post-workout supplement for muscle growth due to its inclusion of eight grams of pea protein isolate and 500mg of coconut water, which may help you fuel after your toughest workouts. In addition, the 500mg of bromelain may help speed up the metabolization of proteins and carbohydrates and can also reduce swelling and inflammation. There is also 200mg of Himalayan sea salt, which, along with the coconut water, can help replace electrolytes.




Swolverine POST









Swolverine's POST vegan post-workout powder uses pea protein, carbohydrates, coconut water, and Himalayan sea salt to help you refuel after a hard workout.







Much of POST’s carbohydrates come in the form of fruits like pomegranate, papaya, and pineapple. In addition to the fruits’ antioxidant and anti-inflammatory properties, papaya also contains an enzyme called papain, which may help to aid the digestion of protein.

Best Creatine for Muscle Growth
Creatine can come in many forms, but the one with the most scientific backing behind it is the creatine monohydrate form with decades of research showing that it can be effective for helping muscle growth and strength increases. (3) Many companies try their hand at making the best creatine monohydrate supplement, but this one is our favorite (especially with muscle growth in mind).
Transparent Labs Creatine HMB
Transparent Labs Creatine stands out for its addition of HMB, aka ?-Hydroxy ?-Methylbutyrate. This is a metabolite in the branched-chain amino acid leucine that may help to prevent muscle breakdown, so you can retain the muscle that you already have while packing on more. Combined with creatine, this may help build strength and size better than creatine or HMB alone.

Transparent Labs Creatine HMB









This top-tier creatine supplement from Transparent Labs incorporates HMB to possibly increase strength and preserve muscle more than taking either supplement alone. This is a high quality product that comes unflavored, or in a variety of tasty flavors.







The Bioperine included is a version of black pepper extract, which may help the body absorb the creatine and HMB, so less goes to waste. It also comes in seven flavors, so you’ll probably find one that you enjoy. If you want to stack it with other supplements or mix it with a flavored drink, there’s an unflavored option as well.

The combination of creatine and HMB may be especially effective in helping athletes gain and retain their muscle mass. Plus, the black pepper can help ensure that fewer of the ingredients go to waste.

Best Beta-Alanine for Muscle Growth
Beta-Alanine may be best known for leaving your body feeling tingly once you take it, but the potential effects of beta-alanine on muscle growth and better cognition are the real reason to add this to your supplement stack.
Swolverine CarnoSyn Beta-Alanine
Beta-alanine is a common ingredient in many pre-workouts and has been found to have numerous benefits for training including better mental cognition and mental resilience during tough workouts. (7) Better mental toughness can allow the body to push past the mental limits we’ve set to push harder and work out with greater workout intensity, which may help optimize muscle growth. Another study found that beta-alanine can increase training performance, and may lead to greater progressive overload and adaptations in strength. (8)

Swolverine Carnosyn Beta-Alanine









When you need pure beta-alanine and nothing else, Swolverine Carnosyn Beta-Alanine provides five solid grams per serving. Plus, it offers up 100 servings per container.







Swolverine contains 5,000 mg of CarnoSyn beta-alanine and nothing else. CanoSyn is a patented ingredient and is the only beta-alanine that has status with the FDA as a New Dietary Ingredient. This means that the ingredient was not marketed as a dietary supplement in the United States before October 15, 1994. At $0.91 cents per serving and coming in an unflavored blend, Swolverine’s CarnoSyn beta-alanine is easy to add to any pre-workout beverage or intra-workout beverage to help you find that extra push in your effort. Plus, we think a simple and straightforward beta-alanine supp may be the best way to use the ingredient to hone in on your gains.

Who Shouldn’t Buy Swolverine CarnoSyn Beta-Alanine

Those who prefer to take their beta-alanine in pill form can find beta-alanine pills on the market for their convenience.

Swolverine has created a straightforward and effective beta-alanine product that boasts status with FDA approval. We think this is a simple, yet top-tier choice for anyone who may want to improve their mental resilience and push their workouts further for a better chance at building muscle.
Best Betaine Supplement for Muscle Growth
Huge Supplements intra and post-workout supplement is stacked with important ingredients to potentially help your recovery for your most-advantageous muscle growth. The 3,000 mg of betaine and 5,000 mg of creatine here stick out as the stars.
Huge Supplements Formula XII
Huge Supplements Formula XII has several stand-out ingredients including creatine, and beta-alanine, but the star of the show is the 3,000 mg of betaine included in the formula list. Betaine has been shown to have potentially positive effects on endurance training, possibly allowing the user to perform higher repetitions in the gym. (9) Better endurance can potentially lead to more muscle. This formula also includes 5,000 mg of creatine, which is a huge addition to this line-up due to creatine’s potential to promote muscle growth (4).




Huge Supplements XII Intra & Post Workout









This supp contains 10,000mg of Cluster Dextrin, 5,000mg of Organic ModCarb, 3,200mg of Beta-Alanine, 3,000mg of Betaine Anhydrous, 150mg of Potassium Citrate, and 5mg of Bioperine, which can help you absorb all these nutrients. It comes in Candy Apple and Tropical Blast.







Huge Supplements also added Bioperine to their formula, which may help with better absorption of supplements in the body. Formula XII comes in two delicious flavors to choose from — Candy Apple and Tropical Blast. Each serving costs $2.16, which may be a higher price point compared to others on the market. We believe the line-up of ingredients in this supplement is well worth the price tag though if you can swing it.

Best BCAAs for Muscle Growth
BCAAs, or branched-chain amino acids, are three essential amino acids leucine, isoleucine, and valine. BCAAs have a few benefits — they may help you recover from DOMS and get you back to training sooner, and this solid dose of 4,500mg of BCAAs combined with Onnit’s Power Blend™ may be just what you need to get your muscles growing. (10)
Onnit Total Strength + Performance
This formula has three potent blends with one focusing on BCAAs in particular, though the entire formula is made for performance and recovery. The BCAA blend contains a 4,500mg blend of BCAAs, glutamine, and beta-alanine, which may help with performance in the gym, as well as recovery and endurance during longer training sessions. (10)(11) The support blend headliner is resveratrol, which may also help you push through difficult sets and potentially act as an antioxidant.

Onnit Total Strength + Performance









Onnit contains a Power Blend with longjack, which can help fuel muscle contractions, a Performance Blend with BCAAs, glutamine and beta-alanine, which can help boost performance during exercise, and a Support Blend with resveratrol that can help you push through during tough training.







The power blend features d-aspartic acid, longjack extract, and stinging nettle — all of which may potentially increase testosterone levels to aid in muscle growth. The one downside is that this product only comes in two flavors — Strawberry Lemonade and Pink Grapefruit — so if you don’t like either of those flavors, you may be out of luck. The price is quite reasonable at about $59.99 for a 30-serving container ($2.00 per serving). Onnit has their products third-party tested for purity and potency, so you can rest assured that what’s on the label is what you are actually ingesting.

Best Vegan Protein Powder for Muscle Growth
Who says you can’t get jacked on a vegan diet? With the correct resistance training, nutrition program, and supplementation, your ability for muscle growth can definitely match that of your omnivorous counterparts. This vegan protein may play a key role in your gains with the combination of pumpkin and pea protein.
Swolverine Plant Protein
This vegan protein powder contains two types of protein — pumpkin and pea — and delivers 22 grams of protein per serving. With only 130 calories, two and a half grams of fat, and three grams of carbs, this protein supplement is pretty comparable in macronutrient breakdown to a whey protein isolate, which is notoriously high in protein and low in fat and carbs. This breakdown can be beneficial for those who want to potentially put on muscle mass with high protein while allowing more flexibility in the type of fats and carbs you’re intaking.




Swolverine Plant Protein









This plant-based protein is made from pea isolate, hemp protein, pumpkin seed protein, sacha inchi, and quinoa. It's also pretty low in fats and carbs, boasting only 0.5 and seven grams, respectively.







Due to the origin of the two types of protein, this supp also has a pretty sweet micronutrient profile including 3mg of niacin, 34mg of calcium, 6mg of iron, 24mg of phosphorus, 2mg of zinc, 8mcg of chromium, 121mg of chloride, 330mg of sodium, and 142mg of potassium. It comes in Salted Caramel and Chocolate Cake flavors and will cost you around $1.75 per serving, which is pretty reasonable for a high-quality protein supplement.
Swolverine Plant Protein
Who Should Buy Swolverine Plant Protein

Vegans who want a blend that contains a healthy dose of protein for muscle growth will appreciate the 22 grams derived from pea and pumpkin seed protein here.
This product is ideal for vegans who prefer to get their carbs and fat from food sources — it has just three grams of carbs and two and a half grams of fat per serving.
Those who are looking for a smattering of micronutrients will enjoy that this formula includes nine various micros, which aren’t very commonly found in protein supplements.

Who Shouldn’t Buy Swolverine Plant Protein

Those who like a robust list of flavor options — this product only offers Salted Caramel and Chocolate Cake flavor options.
If you are looking to bulk, you may want a plant protein with higher carbs and fats.
If you want a vegan protein that isn’t from pumpkin seeds or peas, you may want to find one that is derived from hemp, soy, or a different plant.

A vegan diet doesn’t have to come between you and your gains — all it takes is proper resistance training, well-rounded nutrition, and the help of a stacked protein supplement (like this one) that may help you reach your goals.
Best Citrulline for Muscle Growth
If you’re looking for a supplement that may aid in better blood flow and potentially better pumps — this citrulline product will get you excited about all the muscle growth you may garner.
Onnit Total Nitric Oxide
This product includes a healthy dose of three grams of l-citrulline dl-malate. Citrulline is a non-essential amino acid — compared to essential amino acids — it is created in the body and isn’t necessary to obtain from supplementation. However, the benefits of adding a citrulline supplement to your stack could be the difference between a mediocre workout and an intense one. Citrulline is a vasodilator — it can help widen your blood vessels, which may allow more blood flow to pass through, possibly leading to better pumps during your workouts.


10% Off




Onnit Total Nitric Oxide









This product contains three grams of L-Citrulline DL-Malate, as well as mango fruit powder and fermented beets, which can all play a role in synthesizing nitric oxide. It comes in a sweet Harvest Fruit flavor.

Beets are a natural vasodilator making the opportunity for increased blood flow even more likely. This blend is only offered in one flavor — Harvest Blend — and is $1.99 per serving.
Onnit Total Nitric Oxide
Who Should Buy Onnit Total Nitric Oxide

Athletes looking to potentially increase blood flow during their workouts in order to achieve the max muscle growth possible will enjoy the healthy three grams of citrulline in this formula.
Those who want a citrulline supplement that boasts other ingredients beyond citrulline will be happy to see the addition of the proprietary blend that includes fermented beetroot here.
Folks who like amino acids in their supplements for recovery — this supp contains citrulline and arginine.

Who Shouldn’t Buy Onnit Total Nitric Oxide

Customers who like more variety of flavor options or an unflavored option — this currently only comes in a Harvest Blend flavor.
If you’re looking to save cash, you can find less expensive citrulline supplements on the market.

Adding this supplement to your current stack may be the key to giving you the best blood flow to support your pumps and get you through your tough training session. And this possible increase in blood flow may be just the key you were looking for to unlock more muscle growth.

Best Testosterone Booster for Muscle Growth
Testosterone is a hormone that plays a major role in several functions in the body, but one of the major ones is its positive correlation with boosting skeletal muscle hypertrophy, which may lead to better strength and leg power (12). This is one of our favorite test boosters.
TestoFuel Testosterone Booster
Testosterone is a buzzword in the fitness world, but not many people understand the true potential testosterone can offer in their athletic abilities. This supplement contains 11 ingredients that promote hormonal health and provide the potential for better muscle growth. One of these ingredients is 4,000IU of vitamin D3, which can aid in testosterone production. (13) This formula also includes 2,000 mg of D-aspartic acid, which has been shown to increase testosterone levels naturally in the body. (14) The ingredient lineup also includes oyster extract, which can promote testosterone synthesis in the body. (15)

This heavy-hitting lineup of ingredients can potentially unlock your high testosterone levels, which may push you to unlock new muscle growth. TestoFuel comes with three buying options — the most expensive coming out to $2.16 for a one-month supply of four pills daily. If you opt to buy the two or three-month supply, you’ll score a better price tag and some freebies (such as a month’s worth of TestoFuel, an extra test booster, a video guide, a nutrition book, and free shipping worldwide to go with it).

When it comes to boosting testosterone, this formula may be the key you’ve been looking for to level up your muscle growth. Testosterone can potentially boost skeletal musculature, which may help you on your journey to gain mass.
Best Carnitine for Muscle Growth
Carnitine has been tested and shown to have beneficial effects on training, competition, and recovery after intense workouts. Supplementing with carnitine can contribute to maximizing muscle growth due to its potential to aid in recovery, increase oxygen consumption, and stimulate fat metabolism. (16)
Kaged Muscle L-Carnitine
Kaged Muscle L-Carnitine contains 500mg of l-carnitine l-tartrate, which has been shown to improve recovery and reduce fatigue after intense exercise. (17) This is important for building muscle mass as the reduction of fatigue during a workout can help your body push harder and work out for longer, while recovery will allow you to make your way back to the gym sooner.




Kaged Muscle L-Carnitine









Kaged Muscle L-Carnitine contains 500mg of l-carnitine l-tartrate and nothing else in its formula. It requires you to take one pill per serving, which is unflavored, and very budget-friendly.







This is a straightforward carnitine supplement, as it contains no other active ingredients outside of 500mg of carnitine. You’ll only have to take one capsule per serving, and it’s friendly for vegan and plant-based folks. It’s also affordable for any budget as each pill comes out to around $0.12, and the bottle contains 250 vegetable capsules.

Best Carb Supplement for Muscle Growth
Carbohydrates are one of three macronutrients and are the main source of energy for our bodies to function — they can also be a catalyst for muscle growth due to their potential to provide quick energy. The body can use available carbohydrates for energy instead of breaking down muscle tissue.
Transparent Labs Carb Powder
Carbohydrates are an extremely important part of your diet, and they are the main source of energy that fuels your body. One study found that high carbohydrate diets can improve physical performance between two and three percent. (18) Transparent Labs created a carb powder that can be taken pre, intra, or post-workout to make sure your carbohydrate levels are working in your favor.




Transparent Labs Carb Powder









This carb supplement is gluten-free, non-GMO, and excludes all artificial coloring and perservatives. Each serving packs 25 grams of patented Cluster Dextrin®.

Benefits of Supplements for Muscle Growth
The vast majority of supplements are targeted at either improving muscle growth or supporting weight loss. If you’re looking to pack on the beef, then adding a few muscle growth supplements may be a way to help move things along more effectively. On this list, there are supplements that aim at improving recovery, helping to supplement your diet, and even potentially boosting your workout performance.
Improved Recovery
If you put a ton of effort into training and then none into recovery, your results are likely not going to be optimal. There are countless ways to potentially enhance recovery, from cold plunges and saunas to post-workout supplements and protein shakes, like the ones we’ve included in this list. Picking up a high-quality recovery supplement may be the missing piece of your puzzle to unlocking more muscle growth.
Diet Supplementation
As the old saying goes, abs are made in the kitchen. That holds true for muscle growth too since proper diet is of paramount importance for seeing the most return for your lifting efforts. You can hit it hard in the gym every day, but if your nutrition and diet aren’t on point, then you’re likely leaving potential muscle mass on the table.
Supplements like creatine, protein powder, carbs, BCAAs, and others may be the key to unlocking hidden gains. It’s hard to always have proper food ready and available, so you can always supplement your diet with a mass gainer or protein bar when you’re in need of some food and don’t have a way of cooking any or warming up a pre-made meal.
Better Workouts
Adding a pre-workout (or another supplement intended to enhance your workouts) to your routine can be a great way to potentially push harder and longer at the gym. Supplements for muscle growth, like creatine, betaine, beta-alanine, carnitine, and good ole pre-workout, might give you the extra edge you need to push for another couple of reps, or bump up the weight higher than last week, which can result in improved muscle gains.
How We Chose the Best Supplements for Muscle Growth
There are many things to consider when choosing which supplements are best suited to aid in your muscle growth and fitness goals. We looked at four important factors — supplement type, price, research, and dosage to make sure this list delivered to fit your needs.
Supplement Type
We wanted to make a list that would cater to people who were trying to aid their muscle growth, but there were many things to consider. First, we wanted to make sure there were pre, intra, and post-workout options, so that all consumers can find a product that fits with their supplement regimen. We considered various goals, such as mental focus, recovery, blood flow, and of course, muscle growth. We included both individual supplements to help support specific goals, and larger blends that may include various supplements that can help you build muscle.
We also took into consideration that there are a plethora of people that this list caters to. We spent time thinking about gymgoers, athletes, bodybuilders, and people just getting into weightlifting to make sure there is something for everyone on this list.
Price
Depending on what supplement type you choose, the price will vary. Typically, products with more ingredients tend to have higher price tags, while products with singular ingredients have lower price tags. We realize that not everyone is working with the same budget, and have included a wide range of prices on this list. Rest assured though that we think even the highest price tags we placed on this list are worth the cost.
Research
Research is an important factor when it comes to picking the best supplements. We believe that well-researched and backed claims deserve the best spots on our lists. Each supplement, ingredient, and claim for these products are backed by research and is also researched by our team at BarBend. We believe in the integrity of a product and want to ensure that there is research that aligns with each claim made when it comes to these supplements.

We spent time looking at various products for each category and thoughtfully picked the one that we believed best aligned with potentially aiding muscle growth. Whether it was a product that might aid in speedy recovery to help you get back to top performance in the gym quicker or a supplement that might assist your body in utilizing carbs as fuel instead of breaking down muscle tissue — we took every pick into deep consideration.

Dosage
We believe in the products that we back, and make sure we spend the time scouting out each supplement for proper dosages. We try to choose picks that have the clinically-dosed amount of each ingredient for them to be the most effective. As noted in some of the picks, proprietary blends are also a common way that ingredients are added to a supplement.
We always make sure we note when a supplement has a proprietary blend because it means the exact amount of each ingredient in the blend isn’t disclosed. If we pick a proprietary blend, it’s because we value the ingredient list and the integrity of the supplement beyond just the dosage.
How Much Do Supplements for Muscle Growth Cost?
This lineup has a very diverse group of supplements, and therefore, the cost of each supplement will vary depending on its dosage and ingredient list. Some of the supplements come in various buying options, including a one-month supply, two-month supply, or three-month supply — the more you buy, the less you pay per serving.

Muscle growth can be achieved within any budget, but it is important to prioritize each supplement and decide if it fits your budget and your goals, or if it’s just an extra supplement to add to your stack. Our protein powders on this list are both above $2.00 per serving — between about $2.09 and $2.50 — and although both are on the higher end of the price spectrum, they both have high-quality ingredients and high protein content compared to others on the market. Some of our choices that can be taken for pre-workout are between around $0.91 to $1.99 per serving. Depending on your needs for a pre-workout, you can find a supplement that fits your price range here.
Common Types of Muscle-Building Supplements
Some of these supplements focus on muscle growth specifically — like protein and creatine, which both can help with hypertrophy when paired with resistance training. Other supplements on the list are created to help with better blood flow, mental toughness, and boosting hormones, which may, in turn, help with muscle growth.

All of these may aid in muscle growth in one way or the other, but their formulas will vary considerably depending on what supplement you are looking at purchasing. It’s always good to read the ingredients list of each individual supplement, and consult with your doctor if you’re considering adding any of these to your supplement regimen.
Protein
Protein powder is a staple supplement for bodybuilders and your average gymgoers alike. Protein is one of three macronutrients and is the macronutrient that can specifically help with hypertrophy. When it comes to muscle growth, protein may be the most important supplement in your arsenal. Whether you choose between isolate, concentrate, or vegan protein powders like pea protein, studies have shown that supplementing with protein powders can lead to more muscle thickness. (19)
When we put our bodies through resistance training, our muscle fibers tear, allowing them to grow — but it takes the right supplementation to help them grow. Protein powder is a quick and easy way to ensure you get your protein supplementation right after a workout to aid your body while it repairs those muscle fibers for potentially better muscle growth.
Pre-Workout Supplements
Not all pre-workouts are created equal — and as this list demonstrates, a pre-workout doesn’t have to be categorized as such in order to help you make the most of your workouts. Beta-alanine, betaine, and citrulline are all examples of supplements that may be taken within a pre-workout supplement, but can be stacked as standalone supplements, as well. What is important here is to consider when the supplement will be most effective. Beta-alanine, for example, is a great pre-workout supplement due to its potential to help you focus, and because it’s a vasodilator, it may help you get better blood flow for your muscles.

Betaine can have a positive effect on endurance training making it most effective to take before you start your workout. Citrulline is also a vasodilator which can lead to better blood flow and then to better pumps when you are working out. When you take a pre-workout that can aid in endurance and better blood flow, there is more potential to crush your workout, and therefore, attain more muscle growth.
Some pre-workouts are stacked and contain a blend of several of these ingredients. Although they may sport a higher price tag, some pre-workouts contain a list of ingredients that includes betaine, citrulline, and beta-alanine in one package. This delivers a mix of ingredients that may support energy, focus, and better blood flow. It all depends on what muscle growth supp you want to try for yourself.
Post-Workout Supplements
Many of these supplements can also be used post-workout in order to possibly enhance the effects of your workout. Creatine, carb supplements, BCAAs, testosterone, and protein can be beneficial to utilize as post-workout supplements. Carb supplements can be a great post-workout supplement to prolong the effects of carbohydrate supplementation for refueling after a grueling workout.
Likewise, BCAAs can be important to take post-workout in order to maximize the potential muscle growth benefits. When you workout, you are tearing your muscle fibers, and because BCAAs are the building blocks of protein, it would make sense to use them as a post-workout recovery tool to potentially enhance growth.
BCAAs
BCAAs are an example of a supplement that could be used at any point pre, intra, or post-workout. BCAAS are fairly eclectic due to their ability to be potentially effective for several factors, such as recovery and mental focus for tough workouts. (7) They may be taken pre-workout to help with focus, or they may be taken intra-workout to promote hydration and a possible push in endurance.
Credit: VeronikaSmirnaya / Shutterstock
BCAA are also three of nine essential amino acids that are the building blocks of protein, so they may be best utilized during or after exercise for recovery. No matter if you’re using BCAAs for recovery, focus, or hydration, all of these factors have the potential to help with muscle growth.
Creatine
Creatine is a supplement that has been shown to promote statistically significant increases in strength, fat free mass in the body, and performance for high-intensity training. (4) These reasons alone make it one of the most popular post-workout supplements on the market alongside protein. Creatine, when taken as directed, may increase strength allowing you to lift heavier weights, and may also boost endurance, leading to longer and harder workouts — which in turn, may promote muscle growth.
Carb Powder
Carb powder is another example of a supplement that is best used either intra-workout or post-workout, depending on what you need it for. If you use carb powder during your workout, it may be to try and make the most of slow-release carbs for sustained energy. Someone may take it post-workout instead in hopes that it may produce more energy in the body, and therefore keep hard-earned musculature in place. Glycogen (the form of stored carbohydrates in our bodies) is an important metabolic fuel to keep your body from using muscle instead of glycogen stores for energy. (20)
How to Choose the Right Muscle Growth Supplement for You
Adding supplements to your stack to bulk up and pack on muscle can be intimidating with so many options on the market, and so many factors to consider. Before you dive into your search, here are a few things to mull over.
Defining Muscle-Building Supplements
Before you consider purchasing any supplements to aid you on your journey to becoming swole, it’s a good idea to define what they are. In short, any supplement that can potentially help you add muscle mass to your frame is considered a muscle-building supplement. The list is quite long since there are many aspects to consider. Pre-workouts, protein powders, post-workout supps, creatine, carb powders, and more — the list goes on. Other supplements which may aid in general health and wellness like multivitamins and most herbal extracts are generally not considered part of this category.
Being Realistic
No supplement will be a catalyst for muscle growth without you putting hard work into resistance training and nutrition, as well. With that being said, if muscle growth is your main goal, it’s important to ask what you are lacking in your daily lineup to help you achieve maximum muscle growth. If you’re lacking in hitting your protein goal, adding protein powder would make the most sense. If you’re wanting better focus during your lifts to make sure you’re lifting with a good muscle-mind connection, you may want to add beta-alanine to potentially optimize mental toughness.

It’s important to remember that each person may respond differently to individual products. Make sure that you do your own research, check in with your healthcare provider, and think about what gaps you may need to fill in order to make the most of your workouts and supplementation needs for muscle growth.
Ingredient List
Each product on this list will have a different ingredient list and it’s important to pay close attention to each individual ingredient. Depending on allergies, personal preferences (like being vegan), or specific ingredients you may be looking for, it is always best to thoroughly read the label before buying.
Some of these supplements have each ingredient listed with its amount in milligrams or grams, whereas some are listed as a proprietary blend, and may not disclose the exact amount of each ingredient individually. It is an important step to know what you are looking for in a product and see if the ingredient list matches your needs.
Supplement Type
Each product on this list varies in some way making it unique to potentially helping you build muscle. We created a list that would suit various goals for different types of folks — bodybuilders, athletes, gymgoers, and your everyday person looking to gain more muscle. We picked pre-workout, intra-workout, and post-workout options to make sure that there was a supplement on the list that would fit your needs for muscle growth.
Price
Supplement prices can vary dramatically depending on what you’re looking for. The ingredient list in these supplements varies and therefore their price tags will vary as well. We chose supplements that fit BarBend’s integrity and that we felt were worth their price tag based on their ingredient list, dosage, and supplement type.

A supplement that has a stacked ingredient list will show up at a higher price point, while simpler supplements that have fewer ingredients usually sport a lower price tag. An example of an exception to this would be Swolverine’s whey isolate — this supplement has few ingredients, but the quality of whey isolate makes it a higher price due to its potent protein content.
Potential Side Effects
There are some potential side effects of muscle building supplements to watch out for and keep in mind when you start your new regimen. Obviously, everyone is different and no two people will have the same experience with any given product, but there are some general considerations to watch out for like nausea, discolored urine, fatigue, and shortness of breath depending on what type of muscle building supplements you’re taking.
Pre-workouts, for example, may cause some people shortness of breath or even chest pain from high caffeine doses whereas some protein powders can make you feel nauseated if it doesn’t agree with your stomach. If you experience any negative side effects, you’ll want to seek medical help immediately and we always recommend talking with your health care provider before starting a new supplement regimen.
Final Word
When it comes to building muscle, there are many supplements on the market that can help you as you work toward your goals. It’s important to remember that supplements alone won’t achieve muscle growth, but combined with proper resistance training, a diet of whole foods, and the correct supplementation, your goals are more attainable. This list of supplements is a guideline to what is available on the market to potentially help you build muscle, and it’s important to keep in mind what you’re currently lacking in order to choose the right supplement.
When you’re considering which muscle growth supplement to pick, know that all of these picks have high-quality ingredients, and have been well-researched and tested. All you have to do is figure out what you’re looking to accomplish with the supplement, choose your type of product, and allow this list to help you through the rest.
FAQs
Do I need to take all of these supplements for muscle growth if I want to build muscle?The short answer here is no. You don’t need to take any supplements to see muscle growth; however, if you’re looking to get the most out of your training, it can be extremely beneficial to add supplements to your daily routine. Creatine, for example, is a widely researched and well-regarded supplement that is proven to help promote muscle gains. (2)
It isn’t necessary to see results, but it is a helpful tool. It’s also important to note that you likely won’t see muscle gain without the addition of resistance training, and a healthy diet of whole foods, even if you’re taking the right supplements.
How much are supplements for muscle growth?Since there are so many different types of supplements that people take to try to enhance muscle growth, the range of prices is quite wide from around $25 up to $65 per container. Some of those containers cost quite a bit per serving — as much as $2.50 to $3.00. Others are cheaper and can be as little as $0.10 per serving. On average, you’ll see prices around $1.50 to $2.50 per serving for most supplements.
How do you use muscle-building supplement effectively?The way to maximize the potential gains you’ll receive from any supplement, muscle-building one included, is to take them consistently in the recommended doses. Companies put a lot of effort into figuring out how much of an ingredient people should take for the most effect so it’s usually best to follow the instructions and stay on track with taking your supps consistently for the most effectiveness.
What is the best supplement for muscle growth?There are countless supplements on the market intended to support muscle growth, but sometimes a simple approach might be the most effective. We’re big fans of Transparent Labs BULK pre-workout as it has a variety of well-dosed ingredients that may aid in muscle gain. It contains a large dose of citrulline in order to help support blood flow and recovery. (1) Each scoop also has caffeine for energy and ingredients that can potentially help with focus, like alpha-GPC and taurine. All of these ingredients and more make the formula with 13 active ingredients a great choice if your goal is to pack on lean mass.
What muscle building supplement works the fastestThere is no magic formula that will transport you directly to your goal, but there are certainly supplements whose effects you will notice more quickly than others. Pre-workout is an excellent example since you will usually feel the effects within 30 minutes of taking it. You may be able to push harder, have more energy, and achieve improved pumps right away.
Other supps like protein powders or creatine work over time and you may not notice results for a few weeks.
Are these supplements for muscle growth safe to take?All the supplements that we have on our lists here at BarBend have been researched for integrity of ingredients and effectiveness. It is important to remember that every person is different and the effects of each supplement may vary person to person. However, it is extremely important to always refer to your doctor or a medical professional when adding new supplements to your routine — especially if you have any prior conditions or health concerns.

Many people are looking to make the most of their workouts through their supplementation. Whey protein powders and creatine supplements are two of the most popular products that gymgoers utilize to support their hard work with resistance training. Supplementation can help to improve power output in the gym, and as a result, you may gain strength more quickly and be able to build more muscle than you might otherwise. Of course, it’s more nuanced than that. There are many factors that go into building muscle mass, but the addition of supplements to your hard work (and proper nutrition) can be extremely beneficial.


After spending time sifting through all of the types of supplements available, researching how they may benefit those who are looking to grow muscle, and testing them for ourselves, we gathered up our favorites. Whether your goal is optimizing your hard work in the gym, having better blood flow to promote better lifts, or intensifying your mental toughness, these supplements are all geared toward helping you achieve the most muscle growth. Follow along to decipher which of these best supplements for muscle growth may be missing from your daily regimen.


12 Best Supplements for Muscle Growth

Tag along with Nick English as he breaks down our top picks for the best muscle-building supplements on the market in 2023.






Best Pre-Workout for Muscle Growth
Pre-workout supplements may be your secret weapon for monopolizing your gains before you even touch a barbell. It might help with your muscle growth goals if it’s stacked with the right ingredients. This pick contains massive doses of some potentially muscle-building ingredients, like beta-alanine and citrulline, along with modest doses of others.


Transparent Labs BULK
BULK is a pre-workout with 13 active ingredients coupled with B vitamins for energy and electrolytes for hydration. One of the important ingredients for muscle growth is the 4,000mg dose of beta-alanine that may help increase muscular endurance and delay fatigue, allowing you to go harder for longer in the gym. (1) On top of that, you’ll find ingredients to potentially support blood flow like citrulline (8,000mg) and betaine (2,500mg). The citrulline dose may help you recover more quickly and reduce post-workout soreness to get back after it in the gym faster. (2)

Best Protein Powder For Muscle Growth
A lot of protein powder on the market contains fillers, artificial sweeteners, and ingredients that don’t do much to help you maximize your muscle growth. This company created a whey isolate protein that prioritizes protein and leaves the artificial junk out, allowing the best opportunity to help with your gains.


Transparent Labs Whey Protein Isolate
Transparent Labs Whey Protein Isolate powder packs 28 grams of protein per serving, making it one of the higher protein content powders on the market per serving. Being a whey isolate also means it’s lower in carbohydrates and fats than a whey concentrate. This formula exclusively uses 100 percent grass-fed, hormone-free cows to provide its whey, and it’s free of any artificial sweeteners, food dyes, gluten, and preservatives.






Transparent Labs Whey Protein Isolate





Transparent-Labs-Grass-Fed-Whey-Protein-Isolate-BarBend-Coupon-275x275-1.png






With 8 different flavors and 28 grams of whey protein from hormone-free, grass-fed cows, Transparent Labs Whey Protein Isolate is an excellent way to hit your protein macros.









Transparent Labs’ whey isolate comes in eight delicious flavors — Oatmeal Chocolate Chip Cookie, Chocolate Peanut Butter, Milk Chocolate, Cinnamon French Toast, French Vanilla, Strawberry, Mocha, and Vanilla Peanut Butter. All eight flavors are great on their own or the perfect addition to your daily protein shake. Though this product is a little pricey at $2.00 per serving, we think this is a solid protein powder for muscle growth optimization.

Transparent Labs Grass-Fed Whey Isolate
Who Should Buy Transparent Labs Whey Protein Isolate
  • Athletes and gymgoers who prioritize the sources of their whey isolate will be excited to see that this protein comes from 100 percent grass-fed and hormone-free cows.
  • People who want a generous dose of protein to help with muscle growth will love the 28g in this formula.
  • Anyone who needs to keep protein high and carbs low will appreciate the one gram of carbs and zero grams of fat in this formula.
Who Shouldn’t Buy Transparent Labs Whey Protein Isolate
  • Anyone who is in a bulking phase may want a protein powder with higher macronutrients across the board — this is low in carbs and fats.
  • There’s no unflavored option, so if you’re looking for an unflavored protein, you may want to look elsewhere.
  • If you’re on a budget, you’ll find cheaper options on the market — especially if you aren’t attached to an isolate formula.
Not all protein supplements are made equal, and this one stands above the rest due to its high protein content, all-natural ingredients, and eight delicious flavors.

Best Post-Workout for Muscle Growth
Post-workout fuel is an important part of the muscle recovery process and might be the ingredient that allows you to recover faster and get back into the gym for more intense lifts. The pea protein and electrolytes in this formula can potentially assist in recovery and hydration.


Swolverine POST
This vegan formula is the best post-workout supplement for muscle growth due to its inclusion of eight grams of pea protein isolate and 500mg of coconut water, which may help you fuel after your toughest workouts. In addition, the 500mg of bromelain may help speed up the metabolization of proteins and carbohydrates and can also reduce swelling and inflammation. There is also 200mg of Himalayan sea salt, which, along with the coconut water, can help replace electrolytes.

Swolverine-Post-Workout-Barbend-Coupon-275x275-1.png






Swolverine's POST vegan post-workout powder uses pea protein, carbohydrates, coconut water, and Himalayan sea salt to help you refuel after a hard workout.









Much of POST’s carbohydrates come in the form of fruits like pomegranate, papaya, and pineapple. In addition to the fruits’ antioxidant and anti-inflammatory properties, papaya also contains an enzyme called papain, which may help to aid the digestion of protein.


Who Should Buy Swolverine POST
  • Athletes who want muscle-building ingredients that don’t contain animal products will appreciate the vegan ingredients here.
  • Folks who want a good dose of electrolytes will appreciate the 500mg of coconut water and 200mg of Himalayan sea salt included here.
  • If you’re looking to avoid sugary post-workout supplements, you’ll like that this formula contains less than one gram of sugar.
Who Shouldn’t Buy Swolverine POST
  • Anyone who wants a variety of flavors since this only comes in Chocolate Peanut Butter.
  • Folks who are bulking may want a post-workout supplement with higher fats and carbs to assist in their macronutrient intake.
  • Anyone allergic to peanuts should avoid this post-workout since its only flavor contains peanuts.
This post-workout contains all-vegan ingredients, like pea protein and fruit extracts, that can help you build and maintain muscle mass. The coconut water and Himalayan sea salt can help replenish the electrolytes that you’ve lost in your workout, and the enzyme blend can help reduce post-workout inflammation to assist in your recovery.

Best Creatine for Muscle Growth
Creatine can come in many forms, but the one with the most scientific backing behind it is the creatine monohydrate form with decades of research showing that it can be effective for helping muscle growth and strength increases. (3) Many companies try their hand at making the best creatine monohydrate supplement, but this one is our favorite (especially with muscle growth in mind).


Transparent Labs Creatine HMB
Transparent Labs Creatine stands out for its addition of HMB, aka ?-Hydroxy ?-Methylbutyrate. This is a metabolite in the branched-chain amino acid leucine that may help to prevent muscle breakdown, so you can retain the muscle that you already have while packing on more. Combined with creatine, this may help build strength and size better than creatine or HMB alone.

This top-tier creatine supplement from Transparent Labs incorporates HMB to possibly increase strength and preserve muscle more than taking either supplement alone. This is a high quality product that comes unflavored, or in a variety of tasty flavors.









The Bioperine included is a version of black pepper extract, which may help the body absorb the creatine and HMB, so less goes to waste. It also comes in seven flavors, so you’ll probably find one that you enjoy. If you want to stack it with other supplements or mix it with a flavored drink, there’s an unflavored option as well.

Who Should Buy Transparent Labs Creatine HMB
  • Athletes who want to gain size will like that the HMB may help prevent muscle breakdown.
  • People who want to absorb as much of the creatine and HMB as possible will appreciate the black pepper extract.
  • Anyone who wants a choice of flavors will like the seven options available here.
Who Shouldn’t Buy Transparent Labs Creatine HMB
  • People who are allergic to black pepper should look elsewhere since every flavor of this creatine has black pepper extract.
  • Athletes who are looking for creatine phosphate, hydrochloride, or any creatine other than monohydrate should check out another product.
  • Athletes who want a stimulant like beta-alanine should look elsewhere or stack it with something else since this creatine doesn’t contain stimulants.
The combination of creatine and HMB may be especially effective in helping athletes gain and retain their muscle mass. Plus, the black pepper can help ensure that fewer of the ingredients go to waste.

Best Beta-Alanine for Muscle Growth
Beta-Alanine may be best known for leaving your body feeling tingly once you take it, but the potential effects of beta-alanine on muscle growth and better cognition are the real reason to add this to your supplement stack.


Swolverine CarnoSyn Beta-Alanine
Beta-alanine is a common ingredient in many pre-workouts and has been found to have numerous benefits for training including better mental cognition and mental resilience during tough workouts. (7) Better mental toughness can allow the body to push past the mental limits we’ve set to push harder and work out with greater workout intensity, which may help optimize muscle growth. Another study found that beta-alanine can increase training performance, and may lead to greater progressive overload and adaptations in strength. (8)

Swolverine Carnosyn Beta-Alanine





Swolverine-Carnosyn-Beta-Alanine-275x275-1.jpg






When you need pure beta-alanine and nothing else, Swolverine Carnosyn Beta-Alanine provides five solid grams per serving. Plus, it offers up 100 servings per container.









Swolverine contains 5,000 mg of CarnoSyn beta-alanine and nothing else. CanoSyn is a patented ingredient and is the only beta-alanine that has status with the FDA as a New Dietary Ingredient. This means that the ingredient was not marketed as a dietary supplement in the United States before October 15, 1994. At $0.91 cents per serving and coming in an unflavored blend, Swolverine’s CarnoSyn beta-alanine is easy to add to any pre-workout beverage or intra-workout beverage to help you find that extra push in your effort. Plus, we think a simple and straightforward beta-alanine supp may be the best way to use the ingredient to hone in on your gains.

  • Folks who want a straightforward supplement when they’re focusing on the ingredients that may help with muscle growth will like that this product is just 5,000 mg of beta-alanine.
  • Anyone who likes unflavored options to add to their pre- or intra-workout drink will appreciate that this comes as an unflavored powder.
Who Shouldn’t Buy Swolverine CarnoSyn Beta-Alanine
  • Anyone who wants a stacked beta-alanine supplement will have to look elsewhere — this supplement is strictly beta-alanine.
  • Those who prefer flavored powders will want a different formula because this only comes in an unflavored option.
  • Those who prefer to take their beta-alanine in pill form can find beta-alanine pills on the market for their convenience.
Swolverine has created a straightforward and effective beta-alanine product that boasts status with FDA approval. We think this is a simple, yet top-tier choice for anyone who may want to improve their mental resilience and push their workouts further for a better chance at building muscle.


Best Betaine Supplement for Muscle Growth
Huge Supplements intra and post-workout supplement is stacked with important ingredients to potentially help your recovery for your most-advantageous muscle growth. The 3,000 mg of betaine and 5,000 mg of creatine here stick out as the stars.


Huge Supplements Formula XII
Huge Supplements Formula XII has several stand-out ingredients including creatine, and beta-alanine, but the star of the show is the 3,000 mg of betaine included in the formula list. Betaine has been shown to have potentially positive effects on endurance training, possibly allowing the user to perform higher repetitions in the gym. (9) Better endurance can potentially lead to more muscle. This formula also includes 5,000 mg of creatine, which is a huge addition to this line-up due to creatine’s potential to promote muscle growth (4).






Huge Supplements XII Intra & Post Workout





Huge-Supplements-XII-Intra-Post-Workout-275x275-1.jpg






This supp contains 10,000mg of Cluster Dextrin, 5,000mg of Organic ModCarb, 3,200mg of Beta-Alanine, 3,000mg of Betaine Anhydrous, 150mg of Potassium Citrate, and 5mg of Bioperine, which can help you absorb all these nutrients. It comes in Candy Apple and Tropical Blast.









Huge Supplements also added Bioperine to their formula, which may help with better absorption of supplements in the body. Formula XII comes in two delicious flavors to choose from — Candy Apple and Tropical Blast. Each serving costs $2.16, which may be a higher price point compared to others on the market. We believe the line-up of ingredients in this supplement is well worth the price tag though if you can swing it.

Best BCAAs for Muscle Growth
BCAAs, or branched-chain amino acids, are three essential amino acids leucine, isoleucine, and valine. BCAAs have a few benefits — they may help you recover from DOMS and get you back to training sooner, and this solid dose of 4,500mg of BCAAs combined with Onnit’s Power Blend™ may be just what you need to get your muscles growing. (10)


Onnit Total Strength + Performance
This formula has three potent blends with one focusing on BCAAs in particular, though the entire formula is made for performance and recovery. The BCAA blend contains a 4,500mg blend of BCAAs, glutamine, and beta-alanine, which may help with performance in the gym, as well as recovery and endurance during longer training sessions. (10)(11) The support blend headliner is resveratrol, which may also help you push through difficult sets and potentially act as an antioxidant.

Onnit contains a Power Blend with longjack, which can help fuel muscle contractions, a Performance Blend with BCAAs, glutamine and beta-alanine, which can help boost performance during exercise, and a Support Blend with resveratrol that can help you push through during tough training.









The power blend features d-aspartic acid, longjack extract, and stinging nettle — all of which may potentially increase testosterone levels to aid in muscle growth. The one downside is that this product only comes in two flavors — Strawberry Lemonade and Pink Grapefruit — so if you don’t like either of those flavors, you may be out of luck. The price is quite reasonable at about $59.99 for a 30-serving container ($2.00 per serving). Onnit has their products third-party tested for purity and potency, so you can rest assured that what’s on the label is what you are actually ingesting.

Best Vegan Protein Powder for Muscle Growth
Who says you can’t get jacked on a vegan diet? With the correct resistance training, nutrition program, and supplementation, your ability for muscle growth can definitely match that of your omnivorous counterparts. This vegan protein may play a key role in your gains with the combination of pumpkin and pea protein.


Swolverine Plant Protein
This vegan protein powder contains two types of protein — pumpkin and pea — and delivers 22 grams of protein per serving. With only 130 calories, two and a half grams of fat, and three grams of carbs, this protein supplement is pretty comparable in macronutrient breakdown to a whey protein isolate, which is notoriously high in protein and low in fat and carbs. This breakdown can be beneficial for those who want to potentially put on muscle mass with high protein while allowing more flexibility in the type of fats and carbs you’re intaking.






Swolverine Plant Protein





Swolverine-Plant-Protein-275x275-1.png






This plant-based protein is made from pea isolate, hemp protein, pumpkin seed protein, sacha inchi, and quinoa. It's also pretty low in fats and carbs, boasting only 0.5 and seven grams, respectively.









Due to the origin of the two types of protein, this supp also has a pretty sweet micronutrient profile including 3mg of niacin, 34mg of calcium, 6mg of iron, 24mg of phosphorus, 2mg of zinc, 8mcg of chromium, 121mg of chloride, 330mg of sodium, and 142mg of potassium. It comes in Salted Caramel and Chocolate Cake flavors and will cost you around $1.75 per serving, which is pretty reasonable for a high-quality protein supplement.

Who Should Buy Swolverine Plant Protein
  • Vegans who want a blend that contains a healthy dose of protein for muscle growth will appreciate the 22 grams derived from pea and pumpkin seed protein here.
  • This product is ideal for vegans who prefer to get their carbs and fat from food sources — it has just three grams of carbs and two and a half grams of fat per serving.
  • Those who are looking for a smattering of micronutrients will enjoy that this formula includes nine various micros, which aren’t very commonly found in protein supplements.
Who Shouldn’t Buy Swolverine Plant Protein
  • Those who like a robust list of flavor options — this product only offers Salted Caramel and Chocolate Cake flavor options.
  • If you are looking to bulk, you may want a plant protein with higher carbs and fats.
  • If you want a vegan protein that isn’t from pumpkin seeds or peas, you may want to find one that is derived from hemp, soy, or a different plant.
A vegan diet doesn’t have to come between you and your gains — all it takes is proper resistance training, well-rounded nutrition, and the help of a stacked protein supplement (like this one) that may help you reach your goals.


Best Citrulline for Muscle Growth
If you’re looking for a supplement that may aid in better blood flow and potentially better pumps — this citrulline product will get you excited about all the muscle growth you may garner.


Onnit Total Nitric Oxide
This product includes a healthy dose of three grams of l-citrulline dl-malate. Citrulline is a non-essential amino acid — compared to essential amino acids — it is created in the body and isn’t necessary to obtain from supplementation. However, the benefits of adding a citrulline supplement to your stack could be the difference between a mediocre workout and an intense one. Citrulline is a vasodilator — it can help widen your blood vessels, which may allow more blood flow to pass through, possibly leading to better pumps during your workouts.

This product contains three grams of L-Citrulline DL-Malate, as well as mango fruit powder and fermented beets, which can all play a role in synthesizing nitric oxide. It comes in a sweet Harvest Fruit flavor.









This supplement takes it one step further. It contains 5.87 grams of a proprietary blend that includes fermented beetroot, grape seed extract, apple extract, and acerola cherry extract. Beets are a natural vasodilator making the opportunity for increased blood flow even more likely. This blend is only offered in one flavor — Harvest Blend — and is $1.99 per serving.
