YK11 is a powerful SARM supplement promoting massive lean muscle gains which is a great benefit for those wanting to have an aesthetic and shredded physique. 

YK-11 is a synthetic, steroidal selective androgen receptor modulator (SARM). It is a gene-selective partial agonist of the androgen receptor (AR) and does not induce the physical interaction between the NTD/AF1 and LBD/AF2 (known as the N/C interaction), which is required for full transactivation of the AR. The drug has anabolic activity in vitro in C2C12 myoblasts and shows greater potency than dihydrotestosterone (DHT) in this regard.

YK11 induces muscle cells to make even more follistatin than DHT does (a strong myostatin inhibitor). By working through the androgen receptor, YK 11 is able to product effects just as powerful.
