What is S23?
S23 is a nonsteroidal selective androgen receptor modulator (SARM) with high AR binding affinity and strong tissue-selective activity. Among the most potent SARMs, it produces robust anabolic effects in muscle and bone with strong androgenic suppression of the HPG axis (spermatogenesis inhibition at sufficient doses). Research tool for SARM pharmacology, male contraceptive models, and androgen receptor selectivity studies. Research use only.
Research Applications
High-Affinity SARM Pharmacology
AR binding kinetics, agonist efficacy, receptor conformation vs steroidal ligands
