Raw YK-11 powder (431579-34-9) Description

YK11, also known as Myostine, is considered one of the strongest SARMs on the market. It is a synthetic steroidal selective androgen receptor modulator. The drug has anabolic activity in vitro in C2C12 myoblasts and shows greater potency than dihydrotestosterone (DHT) in this regard. YK11 also is a Myostatin inhibitor. they can help you to gain muscle and lose fat.
