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 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 if 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.

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 1/2-1 serving 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.

I love this stuff, it tastes great. I take 3 times throughout the course of a day if I'm really trying to bulk up. Once with breakfast, once between lunch and dinner, and one more before bed. I usually can't sleep if I have protein in my stomach but this stuff gives me no problems at all. Works great too. Better for bulking season, but if you do some light cardio and abs, you can keep things under control. *

Great product used it many times it's good for post-workout recovery very filling the taste is good but there's just no way that you can put two scoops and 8 or 10 ounces of water it would be like cement so break it up into a couple of scoops of a day to fulfill your protein needs *
