  • It really comes down to simply eating more food. – Alex L Jul 21 '15 at 19:18

Eat more food. More regular food and especially more protein if you want to add quality mass rather than just fat. Don't eat more sugar. Add protein shakes or even gainer shakes (protein + carbs) if that helps.

Also, remember that you have many years of growing left.
