It is a select androgen receptor modulator that I would call one of the most infantile of the SARMs. Meaning that it is not currently being developed by any pharmaceutical company, it is not involved in any clinical studies like Ligandrol and RAD140, and only has two research studies associated with it. YK11 is a very, very experimental SARM. From what we can find, it has never been tested on animals or humans!
The only research study that relates to bodybuilders seeking to use YK11 as a muscle building was one done by a Japanese research team. Here is the study.
Here are the cliff notes on the study
YK11 Is A powerful SARM.
Most SARMs are weak compared to anabolic steroids. However, the Japanese researchers concluded in this study that it is not. It has a powerful androgenic effect, more than DHT
It’s a myostatin inhibitor
In the same study it was shown to increase follistatin, which is a protein that inhibits myostatin. Myostatin prevents muscle mass increases in the body.
The information on this SARM is few and far and in between. Remember there are only TWO studies that have EVER been conducted on it. We have seen so-called experts on SARMs saying that YK11 is not a SARM. We believe this is false. In one of the only studies done on this SARM you’ll see that it is stated the YK11 is indeed a SARM. There is absolutely no evidence that YK11 will do ANYTHING to the human body because it has never been tested on humans or even animals. Everything that is being said by so-called experts about YK11 is simply poppy-cock. The fact of the matter is that nobody knows exactly what YK11 will do in the human body. Could it have side effects that could cause serious health issues? Yes. Does it cause hardening or lean mass gains? Nobody knows.
The fact of the matter there is no evidence whatsoever on how much of this SARM you should actually use. There is absolutely no evidence on how much a human should use to increase muscle mass. All of the so-called experts telling you how much to use is completely poppy-cock. Remember it has never been tested in a clinical study on humans. Everyone posting on the internet how much to use is guessing. They have no idea how much to use. They base their recommendations on nothing but what they are reading on internet forums from people self experimenting on themselves, which is completely Ludacris. Should you use 10mg, 20mg, 50mg, 100mg, 500mg? Nobody can tell you and one’s guess is as good as the next persons. Unfortunately, that is the truth about YK11. There is simply no factual evidence on how much a human should use.
