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 (see Supercharge Your Serious Mass) 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 or 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. Store in a cool, dry place. Contents sold by weight, not volume. Some settling may occur.

Serious Mass

Excellent for a dirty or clean bulk. Strawberry is the best for milk and chocolate for water. No clumps

Great product

Awesome taste and also helps to keep the higher calorie count up when time it tight to make/consume meals. Although 12 lbs bag doesn't last as long as I was hoping but still a great product for the price!

Great mass gainer

It's a big bag of calories, carbs and protein that is perfect for people who want to gain mass. What more do you need to know? It's a little more expensive than other mass gainers out there, but that's the price you pay for dealing with a big brand like ON.
