There literally is no comparison between generic and Pharma. First off, I truly believe generic GH is not GH at all, but one of those GH boosters, ghrp and the like, combined with anti diuretics for that water logged effect.
I just finished a kit of Humatrope and am currently running some geno's. I have run tons of generics in the past, blue to green to thanks and jins. And I would take a 15iu geno pin over 100 iu of generics any day of the week. I saw more after a week of Humatrope at as low as 1iu a day than I did 8-10 iu of anything else. With Pharma GH you drop fat from the get go, and the muscles fill out, not a bloated look but a pumped skin tight look. When I take generics, everything fills out. Feet, hands, face, everything. I basically just felt waterlogged and bloated, hence my belief the generics have anti diuretic meds in them for the visual effect.
My BP goes up on generics from the extra water alone.
If you can only get generic, I would honestly just buy more AAS or a GH peptide, it would be cheaper with the same results.
