Yk11 CAS：1370003-76-1

YK11 can inhibit myostatin production in muscles by attaching androgen receptors. It may induce muscles to produce more folliclestatin, which in turn limits myostatin levels, allowing for increased muscle growth beyond genetic ability. YK-11 inhibits myostatistatin (Myostatin), which means that muscles grow faster and faster. One of the most commonly reported effects of YK-11 is increased pump and muscle fullness, with many users claiming this effect is even greater than when stacked with other muscles. The muscle growth capacity of YK-11, compared to testosterone, far exceeds that of other Sarms.
