In your case at your age I would not advise GH!!
Why not run a cycle of T3 / Clen and low to moderate dosage of Test to protect from muscle loss?? You of course can also through in arimidex to mitigate any water retention. But if the test dosage is low the arimidex will be unnecessary...
The above combo with moderate cardio 3x times a week 20 -30 minute intervals, works wonders on me...
