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 additional 30-45 seconds. Tips: Mixing two scoops of Serious Mass™ with 24 oz. of nonfat or low fat milk instead of water will give you a thicker, creamier, higher-calorie shake.
