ALLERGEN INFORMATION: CONTAINS MILK, EGG, WHEAT (GLUTAMINE PEPTIDES) AND SOY (LECITHIN) INGREDIENTS.

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 (ass "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 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 ½ of a serving daily for the first week and 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 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 part is recommended.

Check with a qualified healthcare professional before using this product if you are under 18 years of age or if you have any known or suspected medical condition(s) including diabetes or hypoglycemia, and/or if you are taking any prescription or OTC medication(s).

Serious Mass Chocolate 2.5 5 2 2
Disappointing I purchased this product to help my son put weight back on following surgery. I was impressed by the healthy ingredients and the lack of saturated fats. My son followed directions carefully; however, he lost weight on this product. Most disappointing was the discovery that there were only 4 SERVINGS in the container. This is a lot of money to pay for only 4 servings, and 4 servings is hardly enough to create significant results. I wish I'd read the small print before we purchased this product. August 24, 2013
Optimum Nutrition Serious Mass Chocolate Great price compared to what is available from local stores. Satisfying chocolate flavor that mixes well, drinks more like a milkshake than an energy drink. Mixes well with bananas. Recommended serving size is a little large. Overall great product. April 7, 2013
