  • Description

    Don't judge a gainer based solely upon its calories per serving. 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 by Optimum Nutrition derives a much higher percentage of its calories from protein-7 premium protein sources to be exact. By also supplying complex carbohydrates, dietary fibre, medium chain triglycerides (MCTs), digestive enzymes, vitamins, essential minerals, and great taste as well, Optimum has created the ideal lean gainer. Pro Complex Gainer was made with quality, not quantity, in mind. Because Optimum understand that you want to get big, not fat.
