YK11

YK11, often called a SARM (Selective Androgen Receptor Modulator), is a unique compound that has gained recognition for its potential to promote muscle growth. What sets YK11 apart is its myostatin-inhibiting properties, which makes it more effective than traditional SARMs. YK11 is known to function as a potent androgen, influencing muscle cells to produce more follistatin—a protein that inhibits myostatin, a natural muscle growth limiter.
