I'm interested in trying Yk-11, but most of the reviews I've seen on Youtube mention bad joint or tendon pain using it?
Can anyone confirm this? Opinions also seem to be that it is a very strong compound.
YK has been faked for years so i wouldn't pay any attention to those reviews.
sarms.forsale is the first sarms company to actually sell legit YK and they have the COA and logs to prove it
