YK-11 is a unique compound acting both as a partial androgen receptor agonist and as a myostatin inhibitor, distinguishing it from conventional SARMs. Research has examined YK-11 for its dual mechanism — androgenic receptor pathway activation alongside suppression of the myostatin (GDF-8) pathway that normally limits muscle growth. Preclinical in-vitro research has demonstrated YK-11's capacity to strongly induce follistatin expression and promote muscle cell differentiation. Its combined SARM/myostatin inhibitor profile makes it a unique and highly studied research compound. PeptideBull provides YK-11 at research-grade purity. Not for human or veterinary consumption.
