unless you are looking to be a pro BB, I would stay away from insulin (unless a doctor monitors you weekly, which is almost impossible). Stay on GH for at least a year and do your normal cycles. GH is not a miracle drug, but if you take it over a long period of time then you will grow. from what I understand is that AAS will help you grow existing muscles but GH will grow more muscle cells and then taking AAS with it you will pump up brand new muscle cells. IMO I think you can keep more gains by taking GH through a whole year (with proper PCT and dieting and training.) So, take your cycles and stay on the GH if you can for a year. Be patient and in about 6 months it will all be worth it.
