Allergen information: Contains milk, egg, wheat (glutamine peptides) and soy (lecithin) ingredients.

Suggested/Recommended/Usage/Directions

Directions: 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. New users may find it beneficial to begin with ½ of a serving daily for the first week and then gradually increase to 1 or more full servings several times a day.

Formulation re: Other

Serious Mass is a weight-gain supplement that can be used to feed serious calorie needs in a variety of different ways.

Suggested/Recommended/Usage/Directions

Between Meals: Drink ½–1 serving of Serious Mass between meals to maintain positive nitrogen balance and support a high-calorie diet. Post-Workout: Begin drinking ½–1 serving of Serious Mass 30–45 minutes following exercise to support maximum recovery. Before Bed: Drink ½–1 serving of Serious Mass about 45–60 minutes before bed to provide nutrients to recovering muscle throughout the night. Note: For best results use Serious Mass combined with intense weight training (3–5 times per week) and a sensible whole foods diet. Also, keep in mind that sufficient recovery between workouts impacts your ability to gain lean mass. Allowing at least 48 hours between workouts involving the same body parts is recommended.
