YK11 is a steroidal SARM (Selective Androgen Receptor Modulator). More specifically, it’s a Myostatin inhibitor. It’s considered to be one of the most powerful SARMs on the market and it’s actually comparable to certain steroids in it
As we said, YK11 is a Myostatin inhibitor. It’s important that we know what Myostatin and Follistatin are to understand how YK11 works.
Myostatin is a protein that reduces muscle mass in our bodies as well as our strength. Follistatin is the antagonist of Myostatin, it increases our muscle mass and strength. Basically, Follistatin keeps Myostatin in place and promotes muscle growth. Myostatin, on the other hand, blocks muscle growth.
YK11 aims to increase our Follistatin levels by inhibiting our Myostatin. Because it inhibits the Myostatin, it’s very effective at keeping our muscle mass because Myostatin can’t promote muscle loss. The results of this are increased levels of Follistatin which very effectively promote great muscle gains.
Almost all sports bodies, including the Olympics, listed YK11 as a prohibited substance because of the unfair advantages that it gives (increased muscle mass, strength, etc.). It’s listed as a banned substance by the WADA (World Anti Doping Agency) and the USADA (the United States Anti Doping Agency).
Don’t use this compound if you are a competing professional athlete.
ost bodybuilders say that they get great results by taking a dosage of 10 to 15mg per day and see very little side effects when taking a dosage like this for the length of 8 weeks. We recommend if you are inexperienced with SARMs to take a dosage of 5m
