YK11 belongs to the group of selective androgen receptor modulators (SARMs). Basically what YK11 does is selectively bind to the androgen receptors in the muscle and bones.
By doing so, it will greatly increase the ability to build lean muscle mass. Because of the fact that YK-11 is selective in its actions, you won’t experience a lot of side effects when experimenting with this SARM.
It also said that YK11 has the ability to reduce myostatin activity, making it a myostatin inhibitor. The YK-11 sarm is definitely one of the strongest ones out there. You can’t really compare YK to LGD-4033 or any other SARM because of how strong it is.
DOES YK11 HAVE SIDE EFFECTS?
First of all, the dosage has a huge impact on the potential side effects. The higher the dosage, the more you will increase the risk of experiencing side effects.
Usually, SARMs don’t really carry any serious side effects but with YK it seems to be a tad different. Because YK11 is so extremely strong there have been people who have experienced side effects when experimenting with this compound. It’s even being said that it’s is considered to be anabolic.
The most reported side effect seems to be aggression. Some people also claim that YK suppresses natural hormone production. This is why often a PCT is recommended after experimenting with YK.
