No PH and no aas before you peak out your natural potential. Doing cycles at your age is stupid in every way, no excuses. If you don't take your natural potential to its limit any kind of cycle will lead to mixed results at best, which can leave you disappointed or even discouraged. Don't do it. Get your diet together and learn everything you can about training. The only supps you should be doing are creatine, multi vitamins, and protein shakes and bars. PH and aas are not magic formulas that will get you something that you couldn't have achieved with out them. Definitely not at your age. Cycles are for breaking through plateaus and making steady gains in the long run. You will regret using gear at your age. It can be a disaster to say the least.
