Purity: ≥ 98% (HPLC Verified)
Product Description
YK-11 is a synthetic steroidal compound that functions as both a selective androgen receptor modulator and a myostatin inhibitor, making it unique among research compounds in this class. Structurally based on the 19-Nor steroid backbone, YK-11 acts as a partial agonist at the androgen receptor whilst simultaneously inducing the expression of follistatin, a natural antagonist of myostatin. Myostatin is a negative regulator of muscle growth, and its inhibition has been shown to produce dramatic increases in muscle mass in preclinical models. Research published in Biological and Pharmaceutical Bulletin demonstrated that YK-11 induced myogenic differentiation in C2C1 cells through AR-dependent induction of follistatin expression. This dual mechanism of AR activation combined with myostatin inhibition represents a novel approach in muscle biology research. This product is provided exclusively for scientific research and laboratory use.
