I would (strongly) advice to start and use the GH along with the AAS cycle, these two has a distinct synergistic effect, then you may (And should as long as the budget permits) continue using the GH while off cycleI haven’t used GH yet. I’d like to in the near future. I get enough water retention from Deca as it is so I will start during post cycle recovery I think? Plan is to take 3 months off after this cycle so I will have to get enough to run 2IU per day for 3 months.
Assume you referred to the length of the usage of GH .....6 months minimum
