Description

Optimum Nutrition Serious Mass is a high-calorie mass gainer designed for athletes who need serious muscle growth and weight gain. Each serving delivers over 1,250 calories and 50 g of premium protein, providing the fuel and building blocks necessary for rapid size and strength development. The formula includes 3 g of creatine monohydrate and glutamine to enhance power output, improve recovery, and support lean muscle preservation during intense training. A complete blend of 25 essential vitamins and minerals helps maintain overall health, immune function, and metabolic efficiency while you push your performance limits. With less than 5 g of fat per serving and no added sugar, the low-fat profile keeps unwanted calories in check, while more than 250 g of carbohydrates replenish glycogen stores for sustained energy. The Peanut Butter flavor mixes easily with water or plant-based milk-just add two scoops to 710 ml and customize with fruit or nut butter for a tasty, nutrient-dense shake. Ideal as a post-workout recovery drink or a calorie-rich snack between meals, Serious Mass supports your goal of gaining lean muscle mass and achieving peak athletic performance.
