Guy your only 15, you can pretty much eat what you want. I was eating 5000 calories/day when I was your age. Plus before i went to bed I'd eat like 5-6 table spoons of Peanut butter for extra calories. You seem pretty lean so you should be taking in a bit more fats.
Most people may tell you different, but in order to bulk up you need to put on weight. It is near impossible to stay lean and gain size.
P.S. everyone wants to see the 600lb loglift. If you can't produce it, you may want to delete your account (since you don't have that many posts)and start over. It may save you some flaming in the long run. Or you can just post the vid and prove the board wrong.
