YK11 12mg (Competitors are only 10mg/ml)


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.

Mild, reversible liver impairment. There has been no noted endogenous testosterone suppression.

Another formulation that is often erroneously categorized as a SARM, YK-11 is a myostatin inhibitor. It does not exactly work directly through androgen receptors as SARMs do. Unlike most other SARMs, it only partially activates the androgen receptors, causing catabolic androgenic activity to increase dramatically. That’s why, it is highly potent. YK-11 targets the follistatin levels and works quite like DTH. While Dihydrotestosterone (DHT) is a natural androgen (male sex hormone) that is responsible for the development of male sex characteristics, like pubic hair, etc., follistatin, a kind of protein naturally found in the human body, maintains balance of myostatin, a hormone that controls muscle growth.
