Don't judge a gainer based solely upon its calories per serving. Because when it comes to gaining lean mass, not all calories are created equally. Unlike typical weight-gain formulas that are loaded with simple sugars and fat, Pro Complex Gainer derives a much higher percentage of calories from protein - 7 premium sources of protein to be exact. By also supplying complex carbohydrates, dietary fiber, medium chain triglycerides (MCTs), digestive enzymes, vitamins, essential minerals and great taste, Optimum Nutrition has created the ideal lean gainer. Pro Complex Gainer was made with quality, not quantity in mind. ON understands that you want to get big, not fat

Optimum Nutrition is proud to bring you Pro Complex Gainer - the worlds premier "lean gainer" supplement. Unlike typical weight gain formulas, ON Pro Complex Gainer derives a much higher percentage of its calories from protein. And, while some "ultra-hardgainers" require 1000, 1200, or even 1500 calorie/serving weight gain products, many athletes can gain quality mass with considerably less. So, in addition to calories, ON Pro Complex Gainer provides a blend of 6 premium protein sources, complex carbohydrates, dietary fiber, lipids, digestive enzymes, vitamins and minerals.
