Are you using it now or planned for future? How's the quality?
I've used both generics and pharma GH (Genotropin) in the past and the effects are hard to gauge subjectively especially at first. I've only used 4IU of GGC's batch so far a couple days ago (doing EOD dosing), anecdotally my sleep was a bit better but this could be up to chance. I'm just cruising at the moment in a relatively deep cut with quite a bit of cardio, so I'm using it to help with muscle sparing and fat mobilization. The only time I've really "felt" GH is when I was blasting with water retaining compounds at which point I get numb arms when I'm trying to sleep.
Speaking strictly about the visual quality of the vials and how it behaved when being reconstituted and injected, everything is in line with generics I've had in the past (which is a good thing). Especially when you consider that GGC's prices are significantly better per kit than I have paid in the past.
