YK-11 – 10mg/mL Solution | 60mL Bottle
For Myostatin Inhibition & Muscle Growth Research – Ultra-Potent Analog
A powerful myostatin inhibitor and analog studied for its potential to dramatically enhance muscle growth through both androgen receptor activation and follistatin upregulation. Often described as a hybrid between other and a steroidal compound, YK-11 has shown anabolic effects far exceeding those of traditional in preclinical research.
Elev8 Labs offers high-purity YK-11 in a 10mg/mL liquid solution, formulated for precision and consistency in advanced research settings.

🔬 What Is YK-11?
A synthetic steroidal analog that binds to androgen receptors and also inhibits myostatin, a natural protein that limits muscle growth. By reducing myostatin and increasing follistatin expression, YK-11 enables extreme lean mass development and strength enhancement in controlled studies—without converting to estrogen or causing typical androgenic side effects.
