Directions of Use

Add 2 heaped scoops of Serious Mass™ to a blender filled with 710ml (24oz) of water. Blend for 45-60 seconds, then add a few ice cubes and, if desired, calorie-contributing ingredients.

Tips: Mixing 2 scoops of Serious Mass™ with 710ml (24oz) of skimmed or semi-skimmed milk 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™ 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 support a high calorie diet.

Post-Workout: Begin drinking ½ – 1 serving of Serious Mass™ 30-45 minutes following exercise.

Before Bed: Drink ½ – 1 serving of Serious Mass™ about 45-60 minutes before bed to provide nutrients to muscles throughout the night.

For best results, use Serious Mass™ combined with intense weight training (3-5 times per week) and a sensible, whole foods diet.
