YK11 Description:

YK11, also known as Myostine, is considered one of the strongest SARMs on the market. In fact, it’s so strong and has comparable anabolic activity to steroids that it may actually be a synthetic steroid that was mislabeled a SARM in the first place.

How YK11 works :

As a relatively new compound, exactly how YK11 works to improve lean muscle mass in humans can only be discussed based on intial in vitro studies.

However, what we do know is that YK11 may be a Myostatin blocker – essentially allowing users to reap continuous gains without stalling and requiring a break in a cycle.

Myostatin is a protein that is released to limit muscle growth to ensure they do not get ‘too large’. It is found predominantly in skeletal muscle, and studies show that individuals with a gene mutation that limits Myostatin production are both stronger and more muscular than those with normal amounts.

YK11 may help to inhibit the production of Myostatin in muscles by attaching itself to the Androgen Receptor. From there, it may induce muscles to create more Follistatin, which in turn limits the levels of Myostatin, allowing increased muscle growth beyond genetic capability.

The confusion over whether Myostatin is a SARM or a steroid lies in the naming convetions (or lack thereof) in relation to newer compounds. Kanno, the original Japanese researcher, discovered that YK11 works via the androgen receptor, which is why he initially claimed it to be a SARM.

Newer research suggests that the backbone of YK11 is identical to those of steroids. In reality, we won’t know for sure until more studies are conducted.

YK11 Benefits

There are 3 primary benefits that have been observed in both initial studies and user-reported reviews.

1.YK11 may block Myostatin, allowing continues 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. 

2.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 [1] 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 less side effects than steroids.

3.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.
