SARMs

Extracted from the Wikipedia article Selective androgen receptor modulator.
Non-medical use
SARMs are used by bodybuilders and competitive athletes due to their anabolic and lack of androgenic effects, particularly in the United States, Europe, and other western countries. Some individuals using SARMs recreationally combine multiple SARMs or take a SARM along with other compounds, although there is no research on combining SARMs. The doses used often exceed those from clinical trials; nevertheless, the fat-free mass gained from SARMs is generally lower than what is obtained with moderate doses of testosterone derivatives. According to one study of SARM users, more than 90 percent were satisfied with their usage and 64 percent would take SARMs again even though a majority experienced adverse effects.
