S-23 化学特性,用途語,生産方法
説明
S-23, the orally bioavailable nonsteroidal SARM, is appreciated by jocks over the world for its one of a kind capacity to improve fit bulk and bone tissue. A more secure option in contrast to anabolic steroid, this particular androgen receptor modulator is incredibly powerful to lose obstinate fat. Considered by numerous individuals as an amazing form of S-4 (Andarine), S-23 is a standout amongst other execution upgrading medications to solidify muscle and increase a grainier stylish look.

Step by step instructions to Use S-23
生物活性
S-23 is a selective androgen receptor modulator (SARM). It binds to the AR (Ki = 1.7 nM) and induces AR-mediated transcriptional activation in CV-1 cells expressing the human receptor when used at a concentration of 10 nM. S-23 increases prostate, seminal vesicle, and levator ani muscle weights in castrated rats. It decreases testicular sperm concentration without reducing mounting behavior or the number of intromissions in intact rats when administered in combination with estradiol benzoate (Item No. 10006487). S-23 (3 mg/kg) also increases preference for sexually active intact males when administered to ovariectomized female rats.
臨床応用
S-23 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.
