XStreamForce SARMs – YK11 is quite possibly one of the most powerful SARMs on the market today, due to its unique nature as both a SARM and a myostatin inhibitor. Not only is YK11 a SARM, which will help promote lean muscle growth, but it also inhibits myostatin, which unlocks your natural bodybuilding potential.

What is YK-11? Is it safe for health? What effects can you expect from using this product? What should you know before you buy? Find answers to these and other questions in the following article.

YK11 belongs to a class of research chemicals known as SARMS, which were initially developed to help treat muscle wasting in cancer patients. Selective androgen receptor modulators, or SARMs for short, have potent muscle building effects, and are generally well tolerated in studies. While they were initially created to help cancer patients combat muscle wasting, bodybuilders quickly caught on, and realized that healthy individuals who took SARMs could experience steroid-like effects. While there isn’t much clinical evidence regarding YK11, anecdotal evidence suggests it’s an incredibly potent muscle building agent. In fact, as we’ll explore soon, lab rats which were given YK11 as treatment experienced absolutely mind-boggling muscle growth and results.

YK-11 is one of the newest products on the market. It’s not very popular at the moment. The main reason for this is the lack of human studies and a very small number of animal studies. For convenience, it is often included in the group of SARMs (Selective Modulators of Androgen Receptors). However, it is not SARM – just like the substances in this group, it binds to androgen receptors but does not affect them.

In reality it is a myostatin inhibitor (it reduces its activity in the body). Myostatin is a protein responsible for inhibiting muscle development by blocking the formation of new muscle fibers and reducing the rate of protein synthesis. The amount of this protein in our bodies not only determines our genetic limit, but also affects the rate of muscle regeneration.
