You could look into a ph. Swole v2 seemed to work well for me. At your age if I was going to use a ph going with one a little mild especially to start with. t-1 by bdc nutrtion would be a good one. Research the hell out of ph's before you do. other good products you may want to look into are s1+,t-1pro. A good creapure creatine +dextrose and ala works good. Diet is crucial. Without a good diet supps are useless. For you I recommend a good whey protien, either prolab creatine+dextrose,ala or swole v2 for now. Read up on 1test and 4ad. As I said , a good starter ph is t1. Make sure to look into anti e's such as nolva, clomid, 6oxo. Definatly a multi vitamin. I never had any luck with ZMA and have never heard much good about nitro this and that. But a good creatine and cleaned up diet is the next logical step with possibly a mild 1test+4ad stack.
