12 pounds of mass gainer for under $50? Sign me up! Like most people who take a mass gainer, I was sick and tired of being skinny. I needed 3 tubs of Super Mass Gainer before I got to the size I wanted, but I'm very happy with my physique now for the first time in my life. Just a solid all-around mass gaining supplement with Dymatize's usual quality ingredients (good protein matrix, 5 grams of BCAAs, 3.5 grams of glutamine per serving).
