Most powerful SARMs in peptides family. YK-11 although lumped into the SARM category is actually a myostatin inhibitor. Myostatin inhibits muscle growth. By inhibiting the inhibitor, YK-11 promotes rapid muscle growth. YK-11 has been shown to be more anabolic than dihydrotestosterone (DHT).
Although just discovered in 2011, YK-11 is quickly developing a reputation as the most powerful SARM.
