S-23

S-23 is a highly potent selective androgen receptor modulator (SARM) developed for advanced laboratory research involving androgen signaling, lean tissue preservation, and metabolic activity. Preclinical studies suggest S-23 binds strongly to androgen receptors in skeletal muscle and bone, making it of interest in investigations focused on strength pathways and body composition models.
Researchers have explored S-23 for its potential role in promoting anabolic signaling while maintaining selectivity compared to traditional androgens. Its high binding affinity has made it a compound of interest in performance-related research and recomposition studies.
S-23 is supplied strictly for laboratory research purposes and is not intended for human consumption.
