YK11, Myostine

Chemical formula:
(17 – alpha, 20E) 17,20 – [(1 – methoxyethylidene) bis (oxy)] 3-oxo-19-norepregna-4, 20 – diene-21 – carboxylic acid methyl ester

Molecular name:



1. Presentation of YK-11:

YK-11, also called Myostine, represents the strongest SARMS available to date on the market of sports supplements. Its

properties in anabolics are so powerful, that it is often compared to synthetic testosterone.

Some people don’t consider it as a true SARMS, but rather a mislabeled steroid.

So is YK-11 a SARM or a steroid?

Its inventor Kanno Yuchiro of Toho University claims that YK-11 is a SARM. However, other researchers point out its molecular structure similar to that of steroids. Even if no basic structure has yet been established, SARMS can be defined by their specific functioning.

So to get back to YK-11, even though its molecular structure is close to that of steroids, it still functions as a SARM.



2. Operation of YK-11:

As YK-11 is a relatively new compound, we can only rely on in vitro studies to accurately detail its mode of operation.

Studies conducted on YK-11 revealed that it was an excellent blocker of
It thus allows its users to gain muscle and strength continuously.

Remember that Myostatin

corresponds to a protein, released in the body to regulate muscle growth. It is mainly located in the skeletal muscles and allows individuals not to become too fat.

Other studies involving individuals with a genetic mutation limiting the production of
production, reveal that these subjects develop greater muscularity and increased strength.

By inhibiting the production of Myostatin production in the muscles, by binding to androgen receptors, YK-11 will therefore stimulate the production of Follistatin. The Follistatin will in turn regulate the levels of Myostatin levels, thus promoting muscle gainbeyond the genetic capacity of the individual.


3. YK-11 benefits:

Through its action, YK-11 brings many benefits.

  • Develops continuous muscle growth
  • Improves muscle strength
  • Limits of fat formation
  • Relieves arthritis
  • Prevents baldness
  • Fight against muscle loss



4. YK-11 side effects:

Like other SARMSs, YK-11 is unique in that it provides the same benefits as anabolic steroids, without the fear of side effects.

However, it should be noted that no studies on animals or humans have yet been conducted. Therefore, we do not know their long-term effects at this time.

Nevertheless, in vitro studies report more than promising results in terms of muscle development and strength gain.

In addition, many user reviews on the forums report that the side effects are side effects are non-existent. Some have reported the slight appearance of acne, which disappears at the end of the treatment.

YK-11 may also cause mild liver damage. However, these lesions are reversible. Indeed, after the end of the treatment, the body naturally repairs these lesions.


5. The different uses of YK-11:

  • To sculpt your body:

THE YK-11 is particularly appreciated in the world of bodybuilding and strongmen. YK-11 works to promote continuous muscle growth and strength development. Thus, a cycle of YK-11 allows to push the limits in terms of muscle volume and strength, without developing any side effects.

  • To limit muscle loss:

Stimulating the production of muscle cells, YK-11 helps fight against muscle loss caused by age. YK-11 represents an excellent alternative to fight against the ravages of old age and allows a maintained toned and firm body.

YK-11 will also be useful for people whose genetic makeup prevents them from acquiring significant muscle mass. Indeed, some individuals naturally have a high level of Myostatin in their body. This high production of Myostatin blocks them in their mass gain, despite the contribution of sports supplements. A course of YK-11 is then the only solution to regulate the rate of Myostatin and thus allow the rapid development of muscle cells. With YK-11, people who are naturally disadvantaged in terms of growth can now develop their muscles according to their goals.

  • To stimulate hair growth:

YK-11 also has the particularity of stimulating hair growth. It is therefore an essential supplement for users who have suffered hair loss following a cycle of anabolic steroids.


6. Initiate a YK-11 cycle:

YK-11 comes in capsule form, to be taken orally. No injectable form is available.

  • Recommended dosage :

It is suggested for men to take 5 to 10 mg, per day, morning and evening, that is to say 10 to 20 mg per day in total. The recommended dose for women is 0.5 to 2 mg per day, morning and evening, for a total of 1 to 4 mg per day.

  • Cycle time:

The cycle lasts 8 weeks, to obtain conclusive results.

  • PCT after a YK-11 cycle: is it useful?

With no no significant side effectsMany users feel that post-cycle therapy is not necessary. Nevertheless, professionals recommend that you perform a mini PCT of 4 weeks, as a precaution, in order to recover the natural functioning of the hormones.

  • The best stack with YK-11:

Most of the time, YK-11 is combined with other SARMSin order to maximize the effects in terms of muscle development and strength increase.

Obviously, the stacks will depend on your goals.

However, one stack stands out for its efficiency: YK-11+ RAD-140

Take 30 mg of RAD-140 and 10 mg ofYK-11 for incredible results. This ultimate stack will accentuate the results in lean mass volume gain, without any water retention.

  • Results with YK-11:

After only one week of cycle, the results are visible in terms of muscle mass gain. However, the results vary from one person to another and according to the diet and training practiced.



7. Is YK-11 suitable for women?

Unlike steroids SARMS in general do not provide no virilizing effect. YK-11 can therefore be used, with complete peace of mind, by women who wish to sculpt their figure.

YK-11 is an excellent excellent alternative to anabolic steroids for people who want to build muscle mass quickly and continuously and maximize their strength, without fear of harsh side effects.
