YK11 is also a myostatin inhibitor (myostatin reduces our muscle mass), which means that you won’t be losing muscle while cutting and will very likely gain some instead, making it a great compound for cutting, lean bulking and especially body recomposition. 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. Testolone, otherwise known as RAD140, has a high affinity for muscle and bone receptors, meaning it will help you build muscle quite rapidly. RAD 140 starts working shortly after ingestion, and begins binding to skeletal muscle androgen receptors, signaling your body to build muscle. In fact, within a week, most users notice an increase in training capability, faster muscle growth, faster recovery, and accelerated fat loss, too.
