Magnus S-23 is a non-steroidal selective androgen receptor modulator that has been demonstrated to increase muscle mass and decrease fat mass, as well as having a high connection to androgen receptors. In contrast to the unfavorable effect of anabolic androgenic steroids, numerous studies have shown it to reduce prostate size. Apart from its muscle and bone tissue-selective anabolic properties, it does not induce the other androgenic effects that typically arise from AAS.
The major impact of using S-23 is that it suppresses the body’s natural testosterone production, making it unique among SARMS. This makes it a viable male contraceptive, though ostarine, andarine (s4), and Ligandrol could have mild effects. Because there have been no human studies, the other potential side effects of S-23 use remain unknown. As a result, it is important to consider all factors when deciding whether to use S-23 or choose a different SARM.
