As a relatively new compound, exactly how YK11 functions to improve lean muscle mass in humans can only be discussed according to initial in vitro research.

Having said that, what we do know is the fact that YK11 may be a Myostatin blocker C primarily enabling customers to reap continuous gains without having stalling and requiring a break within a cycle.

Myostatin is a protein that's released to limit muscle growth to make sure they don't get too large. It is actually identified predominantly in skeletal muscle, and research show that individuals using a gene mutation that limits Myostatin production are both stronger and much more muscular than these with normal amounts.

YK11 could assistance to inhibit the production of Myostatin in muscles by attaching itself to the Androgen Receptor. From there, it may induce muscles to make far more Follistatin, which in turn limits the levels of Myostatin, permitting improved muscle growth beyond genetic capability.

The confusion more than irrespective of whether Myostatin is usually a SARM or perhaps a steroid lies inside the naming conventions (or lack thereof) in relation to newer compounds. Kanno, the original Japanese researcher, found that YK11 works through the androgen receptor, that is why he initially claimed it to be a SARM.

Newer investigation suggests that the backbone of YK11 is identical to those of steroids. In reality, we won't know for positive till extra research are conducted.


There are three key positive aspects that have been observed in each initial studies and user-reported reviews.
  1. YK11 may block Myostatin, allowing continual lean body mass gains

The primary benefit of YK11 and the reason it shows huge promise in the bodybuilding world is its potential to activate more Follistatin in muscles, subsequently blocking the production of Myostatin. By blocking Myostatin, a user could potentially unleash huge gains with continuous muscle growth.

  1. YK11 may be comparable to testosterone in its ability to build strength in muscles

It’s a commonly held belief that while SARMs produce less negative side effects than testosterone, they’re also less effective at creating an anabolic effect in muscle growth.

Initial studies show that muscle cells produce more anabolic factors when exposed to YK11 than they do when exposed to DHT (testosterone). This suggests that YK11 is potentially more powerful than testosterone at producing impressive gains with fewer side effects than steroids.

  1. YK11 shows potential for fast, large gains

Many users report seeing results from YK11 in as little as a single week of use, with the amazing results after an eight-week cycle.
