Buy S-23 Capsules – Potent Selective Androgen Receptor Modulator (SARM) for Muscle Growth Research
Introduction
S-23 is a nonsteroidal SARM developed to mimic testosterone’s anabolic effects with fewer androgenic side effects. It binds androgen receptors with a Ki of approximately 1.7 nM, showing greater affinity than older SARMs like andarine. Research demonstrates that S-23 increases lean muscle mass, enhances bone mineral density, and suppresses sperm production reversibly, making it a candidate for male contraception studies.
While promising, S-23 is still investigational, with limited human safety data. Side effects reported in animal models include testosterone suppression and potential liver toxicity. It is banned by the World Anti-Doping Agency (WADA) and many sports organizations.
