Optimum Nutrition Pro Complex Gainer Optimum Nutrition
Pro Complex Gainer

  • Ultimate lean gainer formula
  • 650 Calories
  • Few sugars
  • 7 Superior proteins including whey, casein, and egg
  • High protein to carb ratio
  • Mixes effortlessly with a blender, shaker, or spoon
  • Easy to drink

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 as well, Optimum Nutrition has created the ideal lean gainer. Pro Complex Gainer was made with quality, not quantity in mind. Because you want to get big, not fat.
