S-23 is available in bulk raw powder form and oral liquid form. Please indicate form in your inquiry message.
S-23 is an investigational selective androgen receptor modulator (SARM),Inc as a potential male hormonal contraceptive.
S-23 binds to the androgen receptor more strongly than older drugs 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 treatment.

S23 can be taken orally, but in this experiment the researchers gave male rats daily injections of S23 for 14 days. The doses varied from 0.01 to 1 mg S23 a day. The human equivalent of these doses - for an adult male weighing 80 kg - would be somewhere between 0.5 mg and 50 mg.
S-23: Boosted muscle mass & Reduced fat mass
S23 not only boosted muscle mass, but also reduced fat mass, as studied. SARMs have a bit of a 'soft' image in the doping world. They don't stimulate muscle growth in the way that anabolic steroids do, but many users say that they are safer. There are no studies yet that confirm this suspicion. But that S23 is not one of the safer SARMs - we’d be willing to wager a bottle of BCAAs on that. S23 halts the production of sperm in the testes. In fact it does this so well that the researchers suspect S23 might be a good candidate for a male contraceptive. If this is the case it would probably have to be part of a cocktail that also contains an estradiol analogue, the researchers discovered. The lab animals lost their libido when they were given S23 on its own, and only recovered this when they were given estradiol benzoate together with the S23.
