What is RAD-140 and what does it do?
RAD-140 (also known as Testolone) is a S.A.R.M discovered in 2010 by Radius Health. It has been shown to have a greater anabolic effect than testosterone, giving greater muscle gains; but a lower androgenic effect, which means less side effects. When combined with testosterone, it amplifies its anabolic effects; but reduced its androgenic effects. This indicates that RAD-140 can make testosterone more effective at muscle building while making it less likely to cause unwanted side effects such as prostate enlargement.
RAD-140 seems to have a dose respondent effect, with increasing doses, increasing the effectiveness.
