this is my opinion, i know uve heard this lots of times, but its true, ur going to need to get A LOT, u sya u eat a lot now, well eat more, stay full, u can only gain weight that way, eat lots of protein, check out alltheywhey.com and get u a bucket of protien, and the AS situation ur looking at, well ur playing soccer, not football, or bodybuliding compitions, so u dont need like a mass load of muscle, but yea i get where ur coming from about gaining weight and muscle. Heres an opinion, and i know that other members on this board will correct me if im wrong, but instead of going to the AS just yet, why not read that book, get on this website and look through these forums and see what people are asking and what the correct answers are, because you might come in that situation sometimes and need the answer to it, thats what i do, ill come get on this website and look around it for like 2 hours, and ive also read 2 books about all this stuff, u wanna me very knowlegable before you get into this stuff, if u start it now, u could possible now get any taller and shoulders not any broader and stuff like that, do ur research on it before you get into it, but here is one suggestion, and guys correct me if u dissagre, not big deal, since your trying to gain weight, and muscle, and every1 is telling you that you need to eat more, get some b-12, do alil research on it, and you could possible try it out, its an injectable, and it increases your energy and increases your appite so you could eat more with it and gain more weight, its a decent solution compared to hitting up the AS at your age, but thats "my opinion". You could do that and get some protien shakes, maybe some creatine, and just eat liek crazy, but hit me back and let me know what ya think, and if ya have ANY questions just start a new forum, these guys have answered so many questions of mine, so just try it. Good luck bro
