YK-11 is a powerful androgenic SARM and an effective myostatin inhibitor! Myostatin is a protein that limits the growth and production of muscle tissue. By inhibiting myostatin, you increase your potential to build muscle tissue.

Japanese researchers at Toho University studied YK11’s role as a myostatin inhibitor. The scientists wanted to know why YK11 was so much more anabolic than other SARMs, so they deactivated follistatin (a naturally occurring myostatin inhibitor). Once the researchers did this, YK11 lost a significant amount of its anabolic properties. This proved that, in addition to acting as an androgen and an anabolic via androgenic pathways, YK11 also acted as a truly effective myostatin inhibitor, significantly boosting its anabolic effects.

More Anabolic than DHT, without the Side Effects

Studies have shown YK11 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. YK11 has the potential to revolutionize not only SARMs but anabolics in general. Its dual mechanism of action and anabolism via dual pathways makes it a truly unique, one-of-a-kind compound.

    Just got done running a bottle of this stuff, awesome Product! would recommend taking at least 10mgs a day. I was just taking 10 mgs a day and I had noticeable gains in strength and size. I feel I would have had even better gains of I was running 15 to 20mgs. But everyone’s body is going to react differently to different doses. I gained a solid 4 lbs running this as a standalone product at 10mgs with just my pre-workout, training and dieting. Didn’t notice any negative side effects. All together I will definitely run this again probably with LGD-4033, or Ostarine I think that would be a great stack.

    I have been taking YK-11 for over three months and absolutely couldn’t be more satisfied. Great product for leaning out, vascularity, and for endurance overall. The Cratus Labs team work diligently to get orders out quickly and accurately. I proudly wear my Cratus Labs shirt as a testament to how satisfied I am and will be in the future as well.
