proper diet and training will get you your results. at your age, PH and steroids will really do you more harm than good. wait till 25 or so. you dont wanna be on testosterone replacement therapy (TRT) or Hormone Replacement Therapy (HRT) for life, trust me. You can take other supplements that will give you good gains though.
AnaBeta by PES, Prime by USP Labs, a pre workout of your choice, Creatine (Creapure or Creatine Nitrate), BCAAs (modern BCAA, iBCAA...etc), Fish Oil and a good multi vitamin would do you a world of good.
As far as test boosters go, there really is no need for them at your age, although i know you will do what you want to do. If you do, here are a few options.
IGF 2 (HGH booster/test booster), DAA (bulk or TCF 1 by PP), Erase, Free Test, HGHup..etc.
hope this helps
