yea you are to young, but most of use started when we were to young, I know I did. So consider waiting bro, I know how hard it is but if you waited afew years you would grow more in the long run. Im not preaching by any means I just had to get that out. Shit I started at 17 against all advise I got, I regret it now cuz I could be growing more now if I woulda listened but fuck it you live and you learn.
500mg test and 40mg Dianabol - methandrostenolone - is a good first cycle. Run the test for 10 weeks and Dianabol - methandrostenolone - 40mg ED the first four.
I usually like and suggest using nova with clomid, but for this simple cycle clomid will be just fine. Drop the tribulus and think about running some HCG - human chorionic gonadotropin - during cycle and then for PCT - post cycle therapy - also. Good luck bro
