Josesph: I'll chime in much like MANY others probably will. (By the way...welcome to "The Forum"!). What should you be considering?
FOOOD, food and MORE food!
Do a search from the main page under "Massive Eating" and digest AS MUCH of that information as you can. Until then...other than a good multi ,AP and perhaps "Surge", don't even worry about any supplements until you know that you're putting down the groceries. (Then the guys on this site can help you with your workout).
But...DIET..."Massive Eating"...is first on the agenda...
