The nutshell in his YK11 video, is that this is the first sarm he took, and basically he loves it, and thinks its definitely the real deal, and produces quality amazing stuff. Tells you to just use your brain if you plan on taking anything (regardless of what it is, sarm, steroid etc), dont be a dumbass. And tells you to go and buy the YK11 because its legal and cheap, before the Fed get their stinking paws on it when they realize how good it is. Another thumbs up for Sarms.
Thanks for the link I watched the video found it a rather entertaining rant (about other stuff) and watched a couple of his other videos also.
