I have used many of the genetic IGF LR3's available from the research chem sites and have had various degress of success with them. This is honestly the best I have done. When I find one that seems to be working well, I stock up. What I would like more than anything, is to get my hands on a kit of Turbovital from Naps. It's made by the same company that makes Hyge. Hyge is IMO, one of the best GH's out on the market and has been for years now. So I'd be pretty damn sure that Turbo is going to be a consistent and well made product. If I were to suggest any brand, this would be the one.
