YK11 is quite possibly one of the most powerful products on the market today, due to its unique nature as a myostatin inhibitor.

YK11 will help promote lean muscle growth, but it also inhibits myostatin, which unlocks your natural bodybuilding potential.

  • Rapid Fat Loss

Your body normally produces something called myostatin, which limits how much muscle you can grow naturally—YK11 inhibits the production of myostatin, unlocking your genetic potential.

It does this by binding to androgen receptors and inducing the muscle cells to produce more follistatin, which inhibits myostatin production.

Using YK-11 requires a PCT (Post Cycle Therapy).

Some side effects may occur such as joint pain. These side effects will subside after completing usage of Yk-11.
