HOW YK-11 WORKS? YK-11 attaches itself to an androgen receptor. This prompts muscle cells to produce more anabolic factors that in turn leads to increased muscle growth. Unlike most SARMS that come with limited androgenic effects, this compound performs much better. In a past study, the effect of this compound on muscle cells was proven to be much higher. In this study, it was found that the muscle cells produced more anabolic compounds when exposed to 500nmol of this compound than when exposed to testosterone. It is safe to say that yk-11 just like any other SARM is designed to help with muscle growth. It has been proven that the compound promotes muscle growth, muscle retention, and the growth of new muscle cells. Its side effects are minimal and cannot be compared to the side effects of steroids available in the market. This possibly explains why it is receiving a lot of attention as many are looking for a solution that is safe and works to enhance muscle growth. This compound works great for those looking to build muscle mass. The compound is also ideal for people who want to maintain the amount and quality of their muscles and keep fat cells at bay.
