YK-11 (Myostine) 10mg x 50 Tablets
$120.00Quick ViewMyostine (YK11) is a promising Selective Estrogen Receptor Modulator (SARM) that is also a myostatin inhibitor and interestingly can also be classified as a steroid due to its chemical structure. Having the potential to build muscle tissue through the unique pathway of inducing follistatin expression, which inhibits myostatin (a protein that limits the amount of muscle one can grow), is something that no other steroid, SARM, or peptide can do, giving this SARM alot of future potential. Due to a lack of clinical studies, the efficacy of this steroidal SARM has not yet been proven.
