Sommaire
YK 11: What is it?
Presentation
YK 11 is a chemical substance known to bodybuilders for its ability to promote muscle development and strengthening. The product is a gray powder with a melting point around 200°C. It is also known as “myostin”.

How it works
YK 11 binds to androgen receptors in the body to optimize follistatin production. It is a protein that plays an important role in stimulating muscle growth. It also prevents or limits the action of myostatin. The role of myostatin in the body is to stop the development of muscles when the natural limit is reached.
YK 11: MRSA or Anabolic Steroid?
What is the main difference between MRSA and an anabolic steroid?
SARM or Selective Androgen Receptor Modulator is a substance that has the ability to attach to certain androgen receptors. However, the compound has specific targets such as bone or muscle tissue. It is therefore less dangerous than anabolic steroids, which affect the liver, testosterone levels and other organs. However, both supplements are effective in increasing muscle mass.
Is YK 11 an MRSA or an anabolic steroid?
Answers to this question remain divergent to this day. Some bodybuilders say it is an MRSA while others say it is an anabolic steroid. In any case, no scientific data is currently available to confirm either of these statements. In any case, these are two equally dangerous categories of products with dangerous health effects.
What are the effects of myostin on muscles?
Increase and conservation of muscle mass
As this compound activates the production of follistatine, it promotes and accelerates the development of lean muscle mass, i.e. free of fat. In addition, it does not cause water retention. This substance is also effective in preventing muscle wasting during slimming diets or the dry period.
Strengthening of bones
Myostin also targets bone tissue and therefore participates in the strengthening of bones. This substance also keeps them healthy. In addition, it stimulates the production of PKB, a protein that is actively involved in the development of bone cells.
So who is YK 11 for?
YK 11 is therefore mainly intended for people who want to achieve greater than normal muscle mass and volume more quickly. It is also a good solution for those who are unable to gain muscle despite extensive training thanks to its ability to inhibit myostatin. Finally, it is suitable for athletes who regularly engage in intense sessions. Its ability to strengthen bones is an interesting asset to minimize the risk of injuries and fractures.
How to take YK 11?
Users of YK 11 suggest taking around 5 to 10 mg per day as part of a slimming diet. The powder is obviously administered orally. You can however go up to 30 mg to develop and strengthen your muscles if your physical conditions allow it. They also advise those who are just starting out to start with the minimum dose to see if the compound is suitable for them. You should stop immediately and consult a doctor quickly if side effects begin to be persistent and/or unbearable.
What are the side effects of YK 11?
Short-term side effects have been observed in some users. They are not as serious as those caused by anabolic steroids, but they do deserve your full attention:
- Headaches and nausea;
- Uncontrolled hair growth;
- Aggression;
- Mild gynecomastia in men;
- Joint pain;
- Decreased libido;
- Muscle hypertrophy in high doses.

No adverse effects on the liver or heart have yet been reported. However, I recommend that you do not consume this compound if you already have problems or insufficiencies at this level.
Is the consumption of YK 11 legal?
The consumption of YK 11 remains illegal in many countries because of the health risks that this molecule represents. In addition, it is considered a doping substance by international sports authorities. Taking it is therefore prohibited for those who wish to compete. You are immediately disqualified and risk severe penalties if you test positive for this compound.
Where to buy YK 11 and at what price?
As I said before, YK 11 is an illegal substance. It is therefore difficult to find it in pharmacies. However, it is still available online since many distributors offer it. The selling price is variable and deliveries are not always safe. I recommend that you pay attention to the reliability and purity of the compound. Poor quality myostin could be very dangerous for your health.
My opinion on YK 11
YK 11 appears to be effective in accelerating and maximizing muscle development. Its short-term side effects also appear to be less dangerous than those of the usual anabolic steroids. I have serious doubts about its long-term effects, especially on the liver and the cardiac system. No studies have been able to answer this question to date. I would therefore advise you to turn to healthier, natural and legal alternatives while waiting for all the scientific data to avoid endangering your health. These substances are also effective and available online. The delivery times are correct.
