As harsh and abrupt as Extreme's comment's are,i agree with him.You opitomise the stereotypical 16 year old and confirm that uninformed attitute with statements like "dude ill take anything even if it helps only a lil"!Not good.I will always take young lads at my gym under my wing and help them anyway i can,they are all like you."yeh,whatever","who care's","just do it","don't be shy" and line's like "urgh,i did'nt know that Gazz" are frequent.We were all 16 once and have all been where you are and i think what Extreme's trying to tell you,at the expense of getting hot under the collar,is that bodybuilding invlove's following the most strict of disipline's that only a Jedi Knight can relate too.
The only thing's that "really work" with regard's to your original question,are your knowledge,dicipline,dedication and will to apply all three to the letter.But that said i'm sure everyone here,myself included,will aid and guid you all they can.
So post up what you eat and how you train and we'll take it from there.
