What is SARM YK11?

You probably have seen our articles about different SARMS such as Ligandrol, Rad140, Ostarine but we have never made an article about YK11 sarm. What is YK11 good for? 

What is YK11?

YK11 is a selective androgen receptor modulator (SARM), which activates AR (androgen receptor) without the N/C interaction. There have been studies that have shown the positive impact of YK11 on myostatin inhibitor. That means it helps to build muscle primarily. Another study suggests that it has the potential to stimulate bone-building proteins to help improve bone health. Even though these studies have confirmed the benefits of YK11 and no side effects, further research is needed. Hence, you can get YK11 in a supplement shop and athletes have said it really helped to increase mass.

How does it work?

YK11 sarm has a similar chemical structure to DHT (dihydrotestosteron – sex hormone) and this is shown by the way it binds to androgen receptors. The body produces DHT naturally for the purpose of promoting prostate health, hair growth, and appropriate puberty development.

YK11 sarm accelerates osteoblast cell proliferation similar to DHT. If you are interested in to more technical terminology, one study claims:

In conclusion, YK11 induces myogenic differentiation via AR-dependent induction of Fst expression. Although DHT did not increase Fst mRNA, both YK11 and DHT elevated the expression of MyHC protein and MRFs’ mRNA, implying that DHT enhances myogenic differentiation through an Fst-independent pathway. In addition to the Fst pathway, YK11 may share this Fst-independent pathway with DHT.

In this report, YK11 was shown to be an appropriate anabolic SARM. However, further investigation is required to elucidate the mechanisms of the differential activation of the Fst pathway by YK11 and DHT.

There is also a discussion about whether YK11 should be called SARM or even steroid. It does indicate how YK11 really works…

YK11 Dosage and timing

According to studies found, the best dosage is between 5-15mg per day. It is recommended to start with the lower dosage and increase if needed.


There are too little studies researching the real benefits of YK11. That is why we provide the information that we have researched and it is based on third party investigations, so we do not take any responsibility. We also consider what our customers said.

  • Increases muscle size
  • The individuals and few tests have concluded that proper YK11 from a good source can really increase muscle mass.
  • Strengthen bones
  • Further studies have shown that YK11 strengthen the bones and help with bone health overall.
  • there was not found yk11 causing suppression


YK11 is maybe the least researched sarm out there. It is very hard to come up with all benefits and all downsides as further research is needed.

YK11 experience

Some customers have gained as much as 5lbs of muscle in 8week cycle and some 2.5lbs. It is very individual. Hope this article helped you to understand what YK11 really is. Always use the recommended dosage and never exceed! YK11 is one of these compounds that you either love it or hate it. Have you found out yet?
