Selective Androgen Receptor Modulators, or SARMs, including YK-11, are a class of therapeutic compounds that have similar properties to anabolic steroids but with reduced androgenic (producing male characteristics) properties. As their name implies, these compounds selectively bind to androgen receptors in the body and can have a more targeted effect than traditional anabolic steroids.

YK-11, in particular, is often discussed in bodybuilding forums and by those interested in muscle growth because it is claimed to be one of the most potent SARMs that helps build muscle with minimal side effects. Here’s how you might describe YK-11 for a supplement store:

YK-11: A Next-Generation Muscle Enhancer

Unlock the potential for rapid muscle gains with YK-11, often considered a cutting-edge performance enhancer amongst fitness enthusiasts and athletes. YK-11 stands apart from traditional SARMs by not just selectively modulating androgen receptors but also by its ability to act as a myostatin inhibitor.

What is YK-11?

YK-11 is synthesized to function both as a SARM and as a myostatin inhibitor, a unique dual-action that could theoretically amplify muscle growth more than any other compound on the market. Myostatin is a protein that inhibits muscle cell growth and differentiation, so by impeding its action, YK-11 may significantly boost muscle growth.


  • Enhanced Muscle Growth: By targeting androgen receptors in skeletal muscle, YK-11 is believed to induce muscle cells to produce more anabolic factors, leading to rapid muscle growth.
  • Strength Gains: Users often report significant improvements in strength, which is invaluable during both the bulking and cutting phases.
  • Myostatin Inhibition: As a myostatin inhibitor, YK-11 may unlock a genetic potential for muscle growth beyond natural limits.
