What is YK 11?
YK 11 Powder is a selective androgen receptor modulator, more specifically, a myostatin inhibitor. Its efficacy is comparable to that of some steroids. As a myostatin inhibitor, YK11 can reduce the level of myostatin in the body, and myostatin is a protein that prevents muscle growth, so it can effectively promote muscle growth. Xi'an Sonwu can provide not only powder, but also capsules, provide OEM service for all SARMS products, and currently have sufficient stock to ship any time. If you feel Interested, please feel free to contact Xi'an Sonwu.

HPLC of Analysis


What are the Functions of YK11?
1. Promotes rapid muscle growth
There is evidence that YK11 is a very potent anabolic drug. It does this by promoting the growth of myostatin, which has been shown to increase lean muscle mass. It is even more proven that YK11 is comparable to some anabolic steroids.
2. Improve muscle stiffness
Studies have shown that YK11 can handle muscle stiffness like any other supplement on the market. Moreover, combining the YK11 with the SR9011 or other SARMS is even more pronounced.
3. Increase muscle strength
Most people take YK11 because of its ability to increase the user's strength rapidly. In an internal medicine study, mice treated with YK11 for only four weeks showed a significant increase in muscle strength. Another study, published in PNAS, found that when mice lacking the myostatin gene were given the drug, the mice were twice as physically active as other mice that didn't use the medicine. While more research is needed on this compound, some evidence has shown that it is a very effective muscle-building compound.
4. Reverse muscle atrophy
While YK11 is known to help increase muscle mass, it can also reverse muscle wasting.
5. Strengthens bones
In a cellular study, YK11 was shown to enhance bone tissue. YK 11 activates PKB (protein kinase B) in mouse osteoblasts, an enzyme primarily used to stimulate bone growth.
6. Reduce body fat
In an animal study, YK11 reduced body fat in mice. Studies claim this is caused by a deficiency of myostatin, which suppresses body fat mass.

How Does YK11 Work?
Myostatin is a released protein that restricts muscle growth and is found primarily in skeletal muscle. Like other SARMs such as, Ostarine, YK11 can inhibit myostatin production in muscles by attaching to androgen receptors. In addition to this, YK11 induces force to produce more follistatin, which in turn limits myostatin levels and increases muscle growth capacity. Inhibition of myostatin means faster and faster muscle growth.
However, YK11 is unique in that it is not only a SARMS but also a myostatin inhibitor, which gives it additional anabolic effects. Our bodies usually produce something called myostatin, which limits the amount of muscle that can grow naturally, and YK11 inhibits myostatin production, thereby unlocking your genetic potential.
Is the YK-11 a SARMS?
YK11 Powder is not only a SARMS, but also a myostatin inhibitor. It acts like other SARMS by binding to androgen receptors in muscles, signaling them to grow. It differs from other SARMS in that it inhibits a substance in the body called myostatin.
Differences between YK11 and SARMS:
Unlike most SARMS, YK11 is a selective androgen receptor modulator or pan-steroid SARMS.
1. Some users using YK 11 have elevated androgen levels, but SARM only affects muscle and skeletal tissue, not other body parts.
2. YK11 increases follistatin levels in the body, but other SARMS do not.
●Follistatin is a hormone that helps increase muscle growth and strength.
3. Most SARMS are full androgen receptor agonists, but YK11 is a partial agonist of AR.
4. YK 11 causes the body to lack myostatin. SARMs do not inhibit myostatin.
Therefore, YK11 not only has the muscle-building effects of a SARM, but also reduces the amount of myostatin in your body, allowing it to surpass its natural muscle-building potential.

Side Effects
1. Testosterone suppression
Some users report a decrease in endogenous testosterone levels after 6-8 weeks of YK 11 use. Of course, compared to other steroids, the effect is less, and it is easier to recover with the help of PCT.
2. Liver toxicity
Due to the steroid nature and structure of YK11, it can stress the liver.
3. Joint pain
4. Hair loss and mild acne
Most of these side effects are caused by the use of excessively high doses of YK 11 and the cycle is too long, so strictly control the dose and ask your doctor for advice before use.
How to Use YK11?
Bodybuilders consider 10 mg to be a good dose for muscle growth and performance enhancement.
The following is the recommended dosage of YK11:
Beginner dose: 10 mg/day
Intermediate dose: 15 mg/day
Advanced dose: 20 mg/day
While some users report taking doses as high as 30 mg/day, most agree that starting with 10 mg to 15 mg is best.
