Im 6'2, 160lbs on a good day. my metabolism is rediculously fast and no matter how much i eat, i just cant gain weight. I got university commin up this summer and im taking a physical education course so i want to be in shape and look big. Right now i hardly have an ounce of fat on me, but have really good muscle definition, i just need to expand it. I have a good workout routine, i just need some advice on what to eat and any supplements to take to add on the pounds. Ive tried a lot of supplements and nothing seemed to work except add water weight.
