A question like this, screams you need to do more research. Not being a dick but there is a whole lot more to making gains than the compounds you pick. Tren comes with many side effects. How many cycles have you done before? & what were they?
I'm not one usually to say not to do something, but if you are in fact 16 like some members are saying you need to hold off for a little while bro; let your body develop naturally before you start pumping it full of test. It's not needed that early in the game.
