How can i gain muscle weight and size fast?

i am 16 6ft - 6ft 1in and am currently going to the gym 3 times a week. i would like to know how to build muscle and get bigger because i am sort of puney looking. i have a skinny frame and i want bigger pecs .wider lats and definatley bigger arms (biceps). i am not against using supplement but i would prefer not to and i will never do any steroids.

i need to know what sort of things i should eat and when and any excercise to bulk up these muscle would be greatly appreciated

My brother goes to the gym and swears by Creatine. You must follow the instructions.
