What?! are you crazy...that's way too many calories...considering that anything over about 1-2 lbs per week of muscle when gaining would be mostly fat that's way too much calorie progress. Your body won't be able to adjust that quickly...that means if you go on a 2 week long bulk and maintain at 2000 calories and weigh about 150, that means 2 weeks from starting you're eating like 500*14+2000 that's something around 9000 cals. I don't think anyone has the time for that and that person's gonna be bloated as hell, fat as hell, and spending money on a bunch of food that's just gonna go to fat. The key is to realize that bodybuilding isn't about gaining weight fast or cutting fast, it's about doing it right.
