What is S-23? S-23 demonstrates a markedly strong bond to androgen receptors S-23 is an modern selective androgen receptor modulator (SARM) with the added interest in its potential for male hormonal contraceptive. It binds to the androgen receptor more strongly than older compounds such as Andarine with a Ki of 1.7nM, and in animal studies it showed both a good ratio of anabolic to androgenic effects, and dose-dependent suppression of spermatogenesis with spontaneous recovery after cessation of research. Added value for research with pronounced suppression of spermatogenesis. Not for human consumption. S-23 Function S-23 not only boosted muscle mass, but also reduced fat mass, as studied. SARMs have a bit of a 'soft' image in the doping world
