Buy YK-11 5mg caps

YK-11 is a synthetic steroidal selective androgen receptor modulator (SARM) and myostatin inhibitor, known for its high affinity for androgen receptors (ARs). It functions as a partial agonist of ARs, exhibiting tissue-selective activity while also modulating myostatin signaling pathways. This compound undergoes hepatic metabolism via oxidation and conjugation, with primary clearance occurring through renal and biliary excretion.
