Description
YK-11 (Myostatin) functions as a partial agonist of the androgen receptor (AR) while uniquely inducing the expression of follistatin, a known myostatin antagonist. By increasing follistatin expression, YK-11 indirectly suppresses myostatin, a negative regulator of muscle growth, thereby enhancing anabolic signaling pathways. This dual mechanism positions YK-11 as both a selective androgen modulator and a functional inhibitor of myostatin-mediated muscle catabolism.
