Personally, I think all this bulking and cutting stuff is rubbish, yo-yo dieting for the lads.
Unless you are a hardcore ectomorph, you are more likely to put on more muscle if you keep your bodyfat in check, so not more that 15% max, and I think that is even pushing it for men, probably between 9-12% would be ideal.
I also don't think that eating anything more than 500-800 kcals above your maintenance each day is very sensible either.
Most of the time, 'bulking' is just an excuse for 85% of the lads to eat rubbbish and get fat.
