Sarms UP MYO BOOSTER active ingredient YK-11 is one of the most advanced compounds currently available on the market. It is a one of a kind substance that works to inhibit Myostatin while working as a Sarm at the same time (Selective Androgen Receptor Modulator). Myostatin is a protein which inhibits and limits muscle growth. Alpha Helix works by binding to Myostatin allowing for one to build tissues to grow beyond the limitations that myostatin normally places on them.

YK11 induces muscle cells to make more follistatin (more than DHT does) – also a strong myostatin inhibitor. With that said, YK-11 can be as powerful as testosterone in terms of muscle tissue strengthening and muscle cell volumisation.


Research suggests Sarms UP MYO BOOSTER YK-11 is effective dosed at 5-10mg per day. Each bottle has 60 caps with 5mg of YK-11. Each bottle contains 30 + dosages. Research cycle length: 6 – 8 Weeks.
