YK11 is typically a synthetic steroidal SARM (Selective Androgen Receptor Modulator). It is echoed to be possibly one of the most powerful SARM on the market today as a consequence of its unique nature to function as both a SARM and a myostatin inhibitor.
Read on to learn more about it, in this ultimate SARM YK11 review.
What is SARM YK11?
As a synthetic steroid, SARM YK11 has been created by changing directly the chemical structure of a particular hormone that naturally occurs in the body called DHT which is a more powerful form of testosterone.
Scientifically there are several theories postulated around the nature of SARM YK11.
The most popular one is that YK11 is a myostatin inhibitor. This theory became popular following a cellular study where it was discovered that YK11 had the possibility of increasing the mass of muscles simply by stimulating the growth and development of a particular myostatin inhibitor called Follistatin which is a very important muscle-building protein.
The other scientific theory postulation is that YK11 is an unusually powerful SARM. This particular theory is centred on a separate study where it was found that YK11 stimulate bone-building proteins.
However, despite the postulations surrounding YK11, the theories are not to be taken as facts as there exists no evidence that backs up the numerous claims. Just like every other SARMS, it is banned by the World Anti-Doping Agency (WADA) making the Supplement illegal for use by athletes and competing bodybuilders.
What does SARM YK11 do?
Just like other SARMs like Ostarine, YK11 works by binding the androgen receptors together in the body which then allows for the growth of skeletal muscles.
YK11 is unique in that it is not just a SARM but also functions as a myostatin inhibitor providing an added anabolic effect. This is particularly very good for its consumers as it ensures that they will fully enjoy the gains and growth of muscles as the days go by.
Also, It can affect DHT-like pathways which are a positive result from its consumption. By simply activating protein kinase B, a signal is sent to the brain to facilitate the creation of cells that build bones and even spur the formation of greater bone growth.

Research Studies
Studies on the in vivo metabolism of the SARM YK11
Scientific data on the metabolism of SARM YK11 is scarce as a result of it being an experimental drug candidate and a non-approved substance for humans.
A steroidal compound was recently detected in a seized black market product and was identified as (17α,20E)-17,20-[(1-methoxyethylidene) bis (oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester. This compound is described to possess selective androgen receptor modulator- and myostatin inhibitor-like properties.
As a consequence of its steroid backbone and the arguably labile orthoester-derived moiety positioned at the D-ring, substantial metabolic conversion in vivo was anticipated. To unambiguously detect urinary metabolites of YK11, an elimination study with six-fold deuterated YK11 was conducted. Post-administration specimens were analyzed using hydrogen isotope ratio mass spectrometry coupled to single quadrupole mass spectrometry to identify metabolites alongside basic mass spectrometric data.
Further characterization of those metabolites relevant to sports drug testing was accomplished using gas chromatography-high resolution-high accuracy mass spectrometry. Fourteen deuterated urinary metabolites were detected comprising unconjugated, glucuronidated, and sulfoconjugated metabolites.
Bone Growth Encouraged
Investigation into the effects that YK-11 has on bone density has revealed that it encourages growth. Yk-11 sends signals to increase levels of activated protein kinase B in cells, resulting in increases in bone growth. Accelerations were found in the cell proliferation and mineralization.

“I used 5mg daily YK11 dosage during my first six weeks cycle. I used a lower dosage to observe how this compound would react with my body. Luckily, everything went well, and the results were remarkable. By the fourth week, I had already gained some muscle mass and lost some body fat as well. I was keen on my diet and preferred one with fewer calories. I was also very active and at times involved in the cardiovascular exercise. This is my new best SARM; at least I do not have to deal with those annoying side effects I dealt with before discovering this unique compound.”

A user on Reddit claimed to have used YK11 orally and witnessed great progress after 8 weeks of usage, with no blood-related complications. He says to have not noticed any side effects except slight lethargy he experienced on the 8th and final week of usage. He says there was no hair shedding and scrotal sac shrinkage.

Users Bradley J and Jamie E were both impressed with their YK-11 purchase. Jamie said that the product was strong, showing massive results. Bradley gained 5kg in muscle mass and feels fantastic. Will combine with other sarms in the next month.
Is SARM YK11 Legal in Australia?
In Australia, YK11 and other SARMs are classified as Schedule 4 prescription only compounds by the TGA. What this means is that in Australia, you can only buy YK11 and other SARMs if you have a doctor’s prescription for it. However, the chances of getting a doctor’s prescription for this supplement are very slim.
It isn’t just difficult to get YK11 and other SARMs in Australia, the illegality of possessing it with no doctor’s prescription comes with a penalty which differs in each state and territory. The maximum penalty for illegal possession is 6 months of a prison sentence.
Buy YK11 in Australia
There are numerous places where you can buy ibutamoren YK11 in Australia.

Australian based company selling a modified version of YK-11 (Nano-YK-7811) that is legal to purchase.
SARM YK11 Dosage and Uses
As a result of the lack of human trials for treatment, there is no medically established YK11 dosage.
Amongst bodybuilders, the generally accepted guideline for muscle growth and enhanced performance is a daily dosage of 10mg , especially for beginners.
However, with as little as 5mg a day (taken over 4-8 weeks), results can be positively seen via muscle gains. Taking beyond the prescribed 10-15mg may result in negative side effects experienced.
- Beginners: 10mg/day
- Regulars: 15mg/day
- Advanced: 20mg/day
