What Is YK11? In the cellular testing that was completed on the YK11 compound, it was determined that it has the capability to significantly grow muscle by way of increasing follistatin which encourages muscle building. YK11 blocks myostatin from being able to perform its duty. Myostatin is a protein that decreases the amount of muscle growth within the body. With it being blocked and follistatin being increased, muscles have the ability to increase in size greatly. YK11 is able to promote bone health by stimulating protein for strong bone building. Those who are involved in bodybuilding can attest that YK11 has incredible fat burning effects with the muscle gains, all with no adverse effects.
