Suggested/Recommended/Usage/Directions

DIRECTIONS: Add two heaping scoops of Serious Mass(TM) 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(TM)" on the opposite panel) and blend for an additional 30-45 seconds. TIPS: Mixing two scoops of Serious Mass(TM) 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 1/2 of a serving daily for the first week and then gradually increase to 1 or more full servings several times a day.

THE TRUE STRENGTH 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, a highly-active metabolism, weaker appetite and on-the-run lifestyle can make it a real challenge to consume enough calories through whole foods alone.

Formula re: Contains
