S23
Product Name: S23
Form: Liquid Solution (30mL)
Concentration: 25mg/mL
Purity: ≥ 98% (HPLC Verified)
Product Description
S23 is a selective androgen receptor modulator developed by GTx Inc., known for its exceptionally high binding affinity and potency at the androgen receptor. It is one of the most potent SARMs identified to date, with research demonstrating strong anabolic effects on skeletal muscle mass and bone mineral density in preclinical models. S23 has attracted significant research interest due to its unique dual potential: studies in male rat models have shown it can decrease spermatogenesis in a dose-dependent and fully reversible manner, making it a subject of investigation as a potential male hormonal contraceptive agent. Concurrently, research has demonstrated its capacity to significantly increase lean muscle mass and reduce fat mass. S23 exhibits full agonist activity at the androgen receptor in muscle tissue while maintaining a degree of tissue selectivity. This product is provided exclusively for scientific research and laboratory use.
