S23 formulation
S23 is an orally available selective androgen receptor modulator or SARM. Originally developed by GTX as a form of hormonal male contraception in rats,it exhibits a high affinity for the androgen receptor with a Ki of 1.7 nM. Researchers, Jones et. Al published a research study comparing the effectiveness of S-23 in both castrated and intact male rats.
In castrated male rats, the effective dose of S23 in the prostate was 0.43 mg/d and 0.079 mg/d in the levator ani muscle. In intact male rats, doses greater than 0.1 mg/d of S-23 suppressed levels of luteinizing hormone (LH) by more than 50%. Furthermore, this dose of S-23 corresponded with decreased size of the prostate and increased size of the levator ani muscle Study. In intact males treated with S-23 as well as estradiol benzoate (to maintain sexual behavior), after 10 weeks there was no sperm found in the testis in four out of the six subjects and no reported pregnancies in all six of the subjects. After the treatment, infertility was completely reversed and 100% of the mating trials resulted in pregnancy.
The effects of S23 on muscle mass and body fat are comparable to the effects of anabolic steroids. In a study conducted in male rats it was discovered that while being treated with S23, the overall body weight and fat mass of the rats decreased. As it was previously mentioned, rats being treated with S23 were also given estradiol benzoate (EB) to maintain sexual behavior. EB is considered an estrogen which is known to cause muscle loss, however, when combined with S23 the effects of the estrogen were canceled out and the muscle mass of the male rats increased Study. . Additionally, in another study using rats, the effectiveness of S23 was tested against muscle loss due to long-term usage of glucocorticoids. This study also looked into the effects of S23 on castration-induced atrophy. In both cases, there was muscle loss but by supplementing S23 and testosterone to the rats the dexamethasone-induced dephosphorylation of Akt is blocked. Overall this study indicated that using S23 may be a more effective way of treating glucocorticoid-induced muscle loss Study.
