Optimum Nutrition is proud to bring you Pro Complex Gainer--the world's premier "lean gainer" supplement. Unlike conventional weight gain formulas, Optimum Nutrition Pro Complex Gainer draws a much higher percentage of its calories from protein. And, while some "ultra-hardgainers" require 1000, 1200, or even 1500 calories/serving, many athletes can gain quality mass with significantly less.
