Does kind of sound like Equigen. Good stuff. I got 30 days out a a bottle a couple of times with no problem. I doubt if any is still around, but the stuff worked, and was about 1/2 the price of "regular" gh. The only thing was it would sometimes give you a little tiny red bump that went away within a few hours, and I recall that there was something wierd about the water you had to use to mix it. You had to use regular sterile water, not Bacteriostatic. I forget exactly why, but I remember that MikeS and I researched the hell out it. He even talked to the manufacturer, and Bacteriostatic water would definitely fuck it up. Maybe someone is making a knockoff, because I'm pretty sure the original manufacturer quit making it. I never was clear exactly what the difference there was with "regular" human gh - I'm not sure there was one, and it worked fine.
If that is what it is, and you get your hands on some, be careful about the water you mix it with - some research might save you spoiling a big bottle.
