YK11 is both a myostatin inhibitor and a SARM making it one of the most potent SARMS you can use.  Japanese research has proven that this SARM can lower myostatin levels in the body.  Myostatin is a protein that prevents muscle growth.

Hi, Alex Rogers here, supplement manufacturing expert.  As a supplement manufacturing expert, I know about quality control and I know how to make quality supplements.  Been doing it for almost 20 years.  When it comes to SARMS, THE most important thing when buying them is a 3rd party lab analysis.  NOT a certificate of analysis.  These are two completely different things.

Listen to my podcast on YK11

My first recommendation to buy YK11 would be Paradigm Peptides.


This is the FIRST company that I have found that actually went out and got their SARMS tested by a 3rd party lab.  In addition, I know of the lab where they got these tests done as I have personally used them for my supplements and other tests.

Thus if you’re looking to buy SARMS and you want to guarantee you are actually getting what your paying for…get them from Proven Peptides.  The ONLY reason I am recommending these guys is because of this 3rd party test.  This is ALL YOU NEED for peace of mind!!

Myostine (YK-11) – This is one of the most popular SARMS on the market.   YK 11 provides the most rapid increase in muscle mass retaining effects even after usage.  YK-11 is a myostatin blocker, which acts as an anti-catabolic compound.


  • Intensive growth of muscle mass without a rollback phenomenon;
  • fat burning;
  • preventing the loss of muscle mass during weight loss and drying;
  • improvement of individual power and speed parameters;
  • increase endurance;
  • biochemical and physiological preventing neuronal damage;
  • improvement of blood circulation;
  • slowing the aging process of cells.


  • Non-toxic;
  • It has no side effects when used correctly.

 What Is YK11 – Its Bodybuilding Uses?

In the bodybuilding world, weightlifting isn’t the only thing you will need, but also diet, supplementation and YK11, a sort of selective androgen receptor modulator (SARM) that encourages anabolic action in the muscle for more rapid muscle gains. But that may seem astonishing, doesn’t it? Well, take a look at the following sections and see what it does to enable you to reach your aims.

YK11: The Research Chemical

Chemists and Japanese researchers are sharp about finding the potentials of the research compound and they failed to go home disappointed. According to first, non-conclusive studies, they discovered that this SARM is accented as it pertains to providing exactly the same effects that typical steroids and muscle boosting medicines can provide to customers.

There’s more to that though, as they also shown that YK 11 works even better than conventional steroids because It’s a stronger anabolic result for the body; in reality, it binds itself to the androgen receptors of the muscle efficiently that it proves to show tremendous effects while at the exact same time inhibiting myostatin effects.

YK11: The Process

Interestingly, the discovery of the compound looked accidental as it was not until Japanese researchers were screening research substance for androgenic properties. But that was among the largest days for athletes and bodybuilders looking to gain massive muscle.

Toho University’s Yuichiro Kanno posted and brought their initial conclusions concerning this SARM and identified that it functions by binding with androgen receptors accountable for creating the side effects of androgens in men, including but not restricted to muscle development and increased aggression.

Generally, other SARMs have little androgenic side effects and comparative anabolic effect if in contrast to conventional testosterone boosters available on the market, but that’s not the case for YK11.

In the publication, He uncovered/exposeds that muscle tissues create more of the anabolic results throughout their contact with the research compound versus if they’re exposed to other compounds like DHT at exactly the same number at 500 nanomoles.

YK11:  The Benefits and Uses

## MUSCLE STRENGTH: It does not come short but really generous of muscle strengthening advantages for users, while the research compound is are new discovery. Muscle tissues subjected to it generates more anabolic results than these uncovered with DHT as suggested within the statement of Kanno.

On that note, it can be safe to say it is best for muscle strengthening, with no detrimental effects caused by steroids that are conventional, including many health hazards. What happens is the fact that it causes muscle tissues, stirring them to produce a higher quantity of follistatin, considerably better than DHT.

Also, it cannot be dismissed this research chemical androgen receptors but doesn’t harm the bones and joints and other body parts where ARs are found because of its particular action/activity.

## MYOSTAT ININHIBITOR: While YK11 continues to be proven to act as an excellent nutritional supplement for building muscle strength, particularly perfect for athletes and bodybuilders, additionally it is found to be a myostatin inhibitor that was great. It valuable as a SARM that acts as a powerful androgen and is unique minus the side effects you may usually experience from injectable options, like prohormones and steroids.

In addition, it works as a myostatin inhibitor. What’s myostatin, anyhow? This can be when it’s present, a kind of protein that restricts the creation and the development of the muscle tissues. By inhibiting myostatin activity so, it is possible to enhance your body’s possible to build muscle tissue that is larger and more slender. But while it seems too good to be true, the scientists have established it.

What happens is that it gradually deactivates follistatin and also inhibits the generation, a myostatin inhibitor. On that note, it could be informed it’s an effective and effective myostatin inhibitor irrespective of its anabolic attributes, which suggests more muscle for you personally!

## MUSCLE DEVELOPMENT: So if you’re appearing to experience bodybuilding results that are exceptional, you might want to contemplate this research compound, which may be taken at doses between 5 and 8 milligrams daily at an eight-week cycle. Nevertheless, you may be worried about estrogen effects but that from the image.

Due to the characteristic that is discerning, It will what it can well but simply on the anabolic action of the muscle tissues for muscle development without unfavorable estrogen effects, that might cause you embarrassment for sporting ‘man -boobs.’

Additionally, this the expression of other genes will not alter in the body because it leaves out the androgen receptors including joints, the bones and prostate. Thus, you can experience great muscle mass building benefits, except the side effects you might have to face if you’ll select steroids that are typical available on the market.

The best part is that it provides all the above mentioned advantages without hurting your body, particularly your liver something which you might need to cope with by selecting other prohormones before any remarkable effects can be attained in the marketplace that might necessitate longer use.

Conclusive details about the compound are not yet been printed and since studies continue to be underway, side effects cannot be noticed at this moment. Based on first and logs findings, there are not any adverse effects noticed at all.
