Introduction

Many users think YK11 is the key to unlocking the body’s full potential and achieving fast muscle gains with few side effects. YK11 appears to be a super-SARM based on the reviews, while in reality, this drug is NOT a typical SARM. Below we break down the science and reviews to give you a clear idea of what to expect from this SARM-steroid hybrid, with risks and side effects.

What Is YK-11?

YK11 is a new synthetic steroid based on 5-α-dihydrotestosterone (DHT), a hormone naturally found in the human body. DHT is a stronger form of testosterone that targets androgen receptors in the prostate, sex organs, hair, and liver. YK11 is gaining interest from bodybuilders due to its ability to quickly build muscle with minimal side effects, much like various SARMs. The structure of YK11 is unique. The YK molecule shares more in common with steroids than SARMs, although it’s often mistakenly placed in the same bucket as all other non-steroidal SARM.

One cellular study suggests that YK11 increases muscle mass. Researchers found that it increases the muscle-building protein follistatin (a myostatin inhibitor). YK11 may also enhance bone health. In a study on bone cells, YK11 increased the levels of bone-building proteins. Some bodybuilders who have experimented with YK11 report great muscle gains and fat loss with minimal side effects. However, there are currently no animal or human studies of YK11 and its safety is unclear.

How Does It Work?

The chemical structure of YK11 is similar to DHT and it binds to androgen receptors in a similar way. DHT is a naturally occurring hormone in the body, crucial for hair growth, prostate health, proper development in puberty. Some bodybuilding resources state that YK11 is one of the strongest SARMs on the market. However, research revealed that YK11 only partially activates androgen receptors and prevents full activation. Such limited activation increases the activity of catabolic androgenic genes.

Importantly, YK11 is also a myostatin inhibitor. A recent cell study uncovered the basis of YK’s unique muscle-building mechanism: increasing follistatin levels. Follistatin is a naturally occurring protein in that suppresses myostatin, which otherwise prevents muscles from getting too large. In comparison, no other SARMs show myostatin inhibition.

YK11 may also increase bone growth by affecting a DHT-like pathway, according to other cellular studies. YK11 activates protein kinase B (PKB), which sends signals to increase the activity of bone-building cells.

So What Does Myostine Do In The Human Body?

YK11 may not be a SARM in the traditional sense, but it has a strong potential to enhance muscle growth. YK11 boosts the growth of muscle cells by increasing follistatin levels, according to cell-based studies. Follistatin suppresses myostatin, a protein that normally stops excessive muscle growth. If the effects of follistatin are blocked (such as with anti-follistatin antibodies), myostatin inhibition doesn’t happen and YK11 loses its muscle-building effects.

YK11 has not been studied in animals or humans.

Anecdotal evidence from bodybuilders suggests it is effective at increasing muscle size. Users report lean muscle gains of up to 15 lbs and a decrease in body fat after a single cycle.

Sex hormones play an important role in maintaining healthy bones. YK11 may be able to bind to androgen receptors in bone tissues and increase bone strength, similar to steroids and SARMs. YK11 increased levels of activated PKB (protein kinase B) in cells. Activated PKB sends signals to increase the growth of bone cells. Strong bones and muscles are both critical for maintaining healthy bones and preventing fractures. Thanks to its muscle-building effects, YK11 may also support bone health, similar to SARMs. This would be especially relevant in older people who struggle with both muscle and bone frailty.

New SARMs are always a hot bodybuilding topic, as their promise to increase muscle mass and burn fat with minimal side effects is appealing to many. YK11 has gained popularity due to its unique way of building muscle by increasing follistatin. There is also some debate on how to classify YK11, as it shares characteristics of both SARMs and steroids.

Positive reviews of YK11 report that it greatly increases muscle mass. Its effects are seen in as little as a week. Some users report no side effects at all or very mild testosterone suppression. However, these claims are clouded by the fact that people use different dosages, cycle lengths, or stack YK11 with other SARMs. Some state that YK11 offers similar results to other SARMs. Many would prefer taking a SARM that is backed up with better research than YK11 if the results are similar. Users also report joint pain that has put them off from using YK11.

Bodybuilders have experimented with YK11 in both bulking and cutting. Allegedly, YK11 is useful in bulking because it builds a lot of lean muscle in a short amount of time. Others have taken advantage of YK11’s ability to burn fat and harden muscles by using it in cutting cycles. There are reports of YK11 causing mild testosterone suppression. Most users agree that post-cycle therapy (PCT) is required.

According to some, YK11 might be ideal for those looking to put on a lot of muscle mass very quickly. All these claims remain purely anecdotal. Users must be cautious, as there is very little information on YK11’s safety and long-term effects.

Dosage

Anecdotal reports suggest the most common dosage is 15-20mg per day, which is a recommended starting dose for new users. Some people report doses as high as 30-40 mg with no side effects. It is usually cycled for 4 to 8 weeks.

Female users report taking doses of 5mg per day.

Anecdotal evidence suggests that stacking YK11 with other SARMs can lead to superior results. Users report stacking YK11 with LGD-4033 or RAD-140.

In Professional Sports

Anabolic agents, including all SARMs, are prohibited in professional sports by the World Anti-Doping Agency. No matter how YK11 is labelled as a SARM or synthetic steroid therefore it is banned in competitions. Despite being a fairly new drug, researchers have already developed a test that can measure YK11 metabolites. The doping test is currently in use and can detect YK11 metabolites for up to 2 days after use.

YK-11 Side Effects

YK11 has only been studied in cells so far. There is no available clinical information on side effects. Not even animal studies have been carried out yet. In a cell study, YK11 increased the levels of follistatin. High follistatin may increase the risk oesophagus, stomach, skin, and prostate cancer. On the other hand, a human study suggests it may be beneficial for breast cancer. The chemical structure of YK11 is very similar to other steroids that are toxic to the liver. YK11 may have toxic effects on the liver as well. Theoretically, it may also affect the prostate, hair growth, vocal cords, and other organs.

Beyond The Science

Given the limited research, information from the bodybuilding community gives more insight into the potential real-world side effects of YK11.

Reported side effects include:

  • Increased aggression
  • Joint pain
  • Low energy
  • Mild testosterone suppression
  • Hair loss
  • Mild acne

YK11 is potentially toxic to the liver. However, some users reported doing blood tests during cycles of YK11 and initial results didn’t indicate abnormal markers of liver damage. Mild testosterone suppression has been reported. To be on the safe side, almost all bodybuilding resources recommend post-cycle therapy (PCT) after a cycle of YK11. Common PCTs include Nolvadex (tamoxifen) and Clomid (clomifene).

Limitations and Caveats

The current research on YK11 is very limited. It has not been studied in animals or humans. All cellular studies on YK11 have been done by one group of researchers from Japan. YK11’s safety and effectiveness can only be evaluated once more research is done.
