What is YK-11

YK11, known as YK-11, or (17-alpha,20E) 17,20-[(1-methoxyethylidene)bis(oxy)] 3-oxo-19-norpregna-4,20-diene 21-carboxylic acid methyl ester as its chemical name, is the newest ingredient in the SARMs family in recent years. YK11 is said to be the most potent SARM without serious side effects such as hair loss, aggression, prostate enlargement, etc. DHT is something people talk with when come across YK11. We may compare them in details in the following.

 

The YK11 molecular is C25H34O6, molecular weight is 430.53. However, the CAS number of YK11 is not unified. One is 137003-76-1;the other is 431579-34-9. If you are confused with the differences, you may drop us a line and we will let you know the details.

 

YK-11 Benefit:

The benefits of YK-11 are that it has shown a strong effect in promoting massive lean muscle gains leading to greater aesthetic and sculpted physique. Many have claim that YK-11 has shown greater muscle gains than many anabolic steroids, but without the androgenic side effects. YK-11 is the most anabolic SARM on the market.

 

YK11 and Muscle strength

YK11 is a relatively new discovery, but actually generous of muscle strengthening benefits for users. As indicated in the report of Kanno, muscle cells exposed to it creates more anabolic effects than those exposed with DHT. YK-11 has been proven to work as a great supplement for building muscle strength, especially ideal for bodybuilders and athletes.

 

What takes place is that it induces muscle cells, stimulating them to create a greater number of follistatin, much better than DHT.

 

YK11 and Muscle growth

Because of its selective characteristic, it does what it does very well but only on the anabolic activity of the muscle cells for muscle growth without the adverse estrogen effects, which may cause you humiliation for sporting ‘man boobs.’

 

Additionally,this compound does not alter the expression of other genes in the body because it leaves out the androgen receptors in other body parts, including the bones, joints and prostate. Therefore, you can experience great muscle building benefits, except the side effects you might have to face if you would choose typical steroids on the market.

 

• Increased Lean & Dry Muscle Mass

• Increase Libido and Performance

• Increase Strength and Stamina

 

YK-11 Dosage:

There is no recommended dose for YK11. Some say that it can be taken at doses between 5 and 8 mg per day at an eight-week cycle, some sports nutrition companies say that the YK11 Muscle Building Cycle should have an administered protocol of 4mg 3 times daily to provide the greatest body composition effects, strength and lean mass. I believe both recommendation for YK11 are right, depending on your own situation.

 

YK-11 Function & Application:

How does YK11 work Simply, YK11 is a myostatin inhibitor as well as a powerful androgen.

 

YK11 as a myostatin inhibitor

Myostatin is a protein that, when it is within the body, myostatin restricts the muscle tissue growth and production. In this way, myostatin is bad to bodybuilders. By inhibiting myostatin, YK11 induces muscle cells to make more follistatin, and bodybuilders can experience significantly more muscle mass and exponential strength increases. In this sense, YK11 can be as good as testosterone in terms of muscle strengthening.

 

YK11 as an androgen

In addition, YK-11 is an androgen. YK11 attaches itself to the AR (androgen receptor), and has been discovered that muscle cells produce more anabolic factors if exposed to 500 nmol (nanomoles) YK11 than if you expose the same muscle cells to 500 nmol DHT. YK11 fortifies parts of your muscles in the same manner as testosterone and the only difference isthat it doesn’t have the additional side-effect. The primary factor to keep in mind about YK11 is it may also provide you with a strengthening boost when you’re during a workout session so apply for longer without encountering any fatigue. On the top of that, it may also help you to modify your body genetics so that you can build more muscle and faster than before.

 

YK11 shows a lot of promise as an apt anabolic SARM. With the muscle growth potential it brings, it’s as effective as anabolic steroids and prohormones without the unwanted side effects connected to the latter.
