The Bigger Picture of Weight Gainers

Serious weight gain requires serious calories. However, those who need the extra calories most, often have the toughest time consuming enough of them. For many aspiring to be bigger, highly-active metabolisms, weaker appetites, and on-the-run lifestyles make consuming sufficient calories through whole foods alone a real challenge. With Serious Mass, you've got nothing to lose and lots to gain. 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. It's time to stop thinking small; get serious-Serious Mass. 1,250 calories per serving in water; 1,630 calories when made with low fat milk. 50 grams of protein from a combination of faster and slower digesting sources including Whey, Casein, and Egg. 250-plus grams of carbohydrate to support fueling of intense workouts and aid in the replenishment of glycogen stores – with NO ADDED SUGAR. Enhanced with Creatine, L-Glutamine and Glutamine Peptide, Choline, Inositol, PABA, and MCTs. 25 Vitamins and Essential Minerals with an emphasis on B-Vitamins and Antioxidants.


Serious Mass is the ultimate in weight gain formulas. With 1,250 calories per serving and 50 grams of protein for muscle recovery, this instantized powder makes the ideal post-workout and between meals shake for sizing up your goals. Serious Mass provides you with the tools you need to pack on the pounds and help you develop the physique you’ve always wanted.


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. POST-WORKOUT: Begin drinking 1/ 2-1 serving of Serious Mass 30-45 minutes following exercise to support maximum recovery. BEFORE BED: Drink 1/ 2-1 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.
