YK-11 – Myostatin Inhibitor & Androgen Receptor Agonist for Research

YK-11 is a synthetic steroidal compound that functions as a selective androgen receptor modulator (SARM) with a unique dual mechanism. It acts as a partial androgen receptor agonist while also inhibiting myostatin – a negative regulator of muscle growth. Preclinical research suggests YK-11 promotes significant follistatin upregulation, leading to enhanced lean muscle accretion, bone density, and muscle fiber regeneration beyond traditional SARM activity. It is studied for applications in muscle wasting disorders, sarcopenia, and androgen deficiency models.

Key Research Applications:

• Myostatin inhibition and follistatin studies

• Muscle hypertrophy and strength research

• Androgen receptor tissue‑selective modulation
