well i was using the underground hgh that voxdeis was selling when he was around.a lot of people know him but he disappeared.to tell you the truth i dont know if the stuff was real or not i should have see better results, but now im on the chinese hgh yes are two leeter friend at 8iu aday and i already see a difference.a lot more energy and feel great so anyway i was on the other stuff for 4 months at 4iu a day and now i started 8iu a day on monday.the only complaint about i have is that it leaves little lumps in my stomach where injected like its not completely dissolved or something.
