Selective Androgen Receptor Modulator / Myostatin Inhibitor
Weekly Protocol Guide
YK-11 Protocol Guide
YK-11 is a unique steroidal SARM that also acts as a myostatin inhibitor. Research suggests it may increase follistatin expression, which inhibits myostatin - a protein that limits muscle growth. This dual mechanism of androgen receptor modulation and myostatin inhibition makes it of particular interest in muscle growth research.
