Almost every preworkout over the last 15 years have contained some form of Arginine. It was the original vasodilator and was in every "NO" product. We now have much better options for a pump. The researchers in the study found something that should confirm to supplement companies that Arginine shouldn't be used in preworkouts anymore. Trained athletes who ingested 6g of Arginine before working out had a 41% decrease in GH and IGF-1 levels postworkout.
Your body naturally releases GH and other growth factors after a workout to help repair and rebuild muscle tissue. Taking Arginine before a workout may significantly hinder your body's natural anabolic response to training! With so many better options for pumps, including citrulline malate and my favorite, organic/inorganic nitrates, arginine is outdated. In fact, citrulline has been shown to raise arginine(and thus NO) plasma levels greater than arginine and nitrates raise them even higher.
