Sarms are great. I run them in my cruises because they are virtually side effect free. Non-toxic to the liver, no effect on lipids (except for lgd-4033), no androgenic side effects, and minimal suppression (except for lgd-4033).
Ostarine (mk-2866) - comparable to tbol. Lean gains, noticeable fat loss if eating at maintenance or below. Expect 4-10lbs of weight gain if bulking. Amazing for recomp. Very minimal suppression. dosage: 10-25mg/day 6-8 weeks. Use mild pct.
S4 - comparable to anavar or masteron. Dry gains, hardening, loads of strength, vascularity. Perfect for cutting. Not ideal for bulking, not much mass to be had with S4. Minimal-moderate suppression. Dosage: 50-100mg/day split twice a day 6-8 weeks. Use mild PCT.
LGD-4033 - Comparable to 500mg test with masteron. By far the most anabolic. Expect up to 10-15lbs of weight gain if bulking. The gains are very lean and dry. Perfect compound for any goal. Moderate-full suppression. Dosage 1-10mg/day 6-8 weeks. Use FULL pct.
*note lgd is highly suppressive and has been shown to adversely affect lipid profile.
