I think I read something about it. It is really a matter of debate, but unless I am mistaken it has something to do with the deep sleep you go into on GHB. Your body produces natural human growth hormone while you sleep, so while on a cycle GHB is supposed to put you in such a deep sleep it helps increase this hormone production as well as assists in recovery. I could be wrong, but I think that is what I got from the article I read. If I was a gear supplier though, I don't think I would stock it either, just due to the stigma that comes with it.
