What is S-23?
S23 is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc as a potential male hormonal contraceptive. It binds to the androgen receptor more strongly than older drugs such as andarine with a Ki of 1.7 nM, 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.
S-23 Main Functions:
S-23 has many potential benefits that range from muscle building and fat loss, to being a possible male contraceptive. Even though this SARM may seem very intriguing, it is still in a very early stage of development and study. Thus, I would proceed with caution when considering this compound. Keep in mind that there are other SARMS on the market today, which give similar muscle building and fat loss effects and are much more studied. Besides, other SARMS will also cause much less suppression of natural testostrone production, allowing the user to run a considerably milder and shorter PCT. All in all, I would recommend sticking to the tried and true until more research is done on S-23. In simple terms, stay away from this SARM until we know more.
This is what gives it potential as a male contraceptive, and also makes it very different from other SARMS. While ostarine (ostabolic), andarine (s4), and Anabolicum (LGD) may cause a mild shut down, S23 is extremely suppressive. Consequently, this will be a major factor in deciding whether to use this SARM or opt for the more widespread choices. Unfortunately, there have not been any human studies, so not much is known on other potential side effects.
