Wow that seems like a long day. Is there a reason you don’t incorporate those small groups of sets into only one or two workouts,
As far a GH I would assume that it would not hurt you to use GH long term it would probably help with recovery, and after exercising all day like that recovery would be optimal.
On your previous post you said your first cycle was 250mg/wk and your second cycle was 1000mg/wk? Did your sides increase from 250-1000?
