S-23 SARM – Potent Androgen Receptor Agonist for Research
S-23 is a next‑generation selective androgen receptor modulator (SARM) known for its high anabolic activity and tissue‑selective properties. Preclinical studies indicate S-23 exhibits strong affinity for androgen receptors in muscle and bone, promoting lean mass accrual, increased strength, and bone mineral density with reduced virilizing side effects compared to traditional androgens. It is primarily investigated for applications such as muscle wasting disorders, hypogonadism, and male contraception research due to its ability to suppress spermatogenesis.
Key Research Applications:
-
Muscle hypertrophy and strength studies
-
Androgen replacement therapy models
-
Male fertility and contraceptive research
