Hey bro, I think you might have some confussion about GH. HGH has nothing to do with test production, so regardless of what you do with your test and with your steroid cycles, you still need to run PCT after. Growth Hormone works indendent of steroids and will do nothing for low test levels. You can use GH while on cycle or while off cycle, though your best results will be when it is combined with steroids. For muscle gains, I would suggest using 4iu or more for at least 16 wks, if not longer. 

Side thought...if you are not getting the results you want from gear, it could be your diet...in fact, that would be my first guess. You need to get enough food in to make the changes you want to make. Gear along, even the best gear in the world, will not make dramatic changes to your body without eating the right meal plan.
