Optimum Nutrition Gold Gainer

Size is an advantage in many sports, but some athletes have a hard time gaining weight. You can only eat so much food, so we formulated GOLD STANDARD GAINER™ with quality calories in a 2:1 ratio of carbohydrates to proteins. Each full-sized serving weighs in at 763 calories with 55 g of high quality complete dairy proteins, mostly from isolate sources to help you grow bigger and stronger when taken in conjunction with an exercise program. The carbohydrate blend includes oat, pea and potato, and the fats include medium chain triglycerides, chia and flax. We took it a step further by making the powder easy to mix in a shaker cup. No blender needed. There is no doubt that GOLD STANDARD GAINER™ raises the bar for weight gain performance.
