I was told by a SOURCE for HGH, that the green top "kigs" are JUST green top generics relabeled. He didn't even try to deny it. HOWEVER.......There is a LOT of chatter right now going on with the Kigtropins. Now it seems that there are tons of fakes flooding the market. The ones with STAMPED date and batch number on the box is supposed to be real, the ones with print is underdosed. Rumors are that the kig factory is behind this. Read around. It is spreading like wildfire.
I know some don't like GH15, but dude knows his shit. You can find out a ton on this on his board.
