I have just turned 17, I'm 5ft 9 and I'm 11 stone(150 pounds). For the past month and a half I have been eating about 3,600 calories on school days and more on the weekends. When I started bulking up I has about a pound or 2 heavy but noticed that I have gotten a small bit bigger. All the foods I eat are healthy and haven't touched junk food for the past month and a half. Should I put chocolate in my diet to help me bulk up?
