MYO (YK-11)

In stock
Product Details

MYO (YK-11) functions as an active myostatin inhibitor and as a SARM. It is one of the newest discoveries and is orally administered. Myostatin is a protein which inhibits or limits muscle cell growth. By inhibiting myostatin the actual amount of muscle that your can build is increased. The normal genetic limit is raised if you will

The thing that makes MYO (YK-11) so interesting and desirable is the fact that it possesses this dual mechanism of action (both SARM & myostatin inhibitor). While there are compounds that work strictly as a SARM and some that work strictly as a myostatin inhibitor, MYO (YK-11) affords you the opportunity to experiment and research with a compound that very effectively acts as both.

Studies have shown MYO (YK-11) to be significantly more anabolic & androgenic than the steroid dihydrotestosterone (DHT) – WITHOUT the adverse side effects of DHT, such as hair loss and prostate enlargement.


Concentration: 10mg/mL
