We've consolidated over 1,250 calories, 50 grams of protein, 250-plus grams of carbohydrate, and 25 vitamins and minerals with added glutamine and creatine into every serving.

Add two heaping scoops of Serious Mass to a blender filled with 24 oz of water. Blend for 45-60 seconds. Then add a few ice cubes and, if desired, other calorie-contributing ingredients (see "Supercharge Your Serious Mass" on the opposite panel) and blend for an addition 30-45 seconds. TIPS: Mixing two scoops of Serious Mass with 24 fl oz of nonfat or low fat milk instead of water will give you a thicker, creamier, higher-calorie shake. New users may find it beneficial to begin with 1/2 serving daily for the first weekend then gradually increase to 1 or more full servings several times a day. Serious Mass is a substantial weight-gain supplement that can be used to feed serious calorie needs in a variety of different ways. BETWEEN MEALS: Drink 1/ 21serving of Serious Mass between meals to maintain positive nitrogen balance and support a high-calorie diet.
