Product Info

  • The ultimate in weight gain formulas
  • Each great tasting chocolate flavour shake contains 1,250 calories per serving
  • Includes 25 vitamins and minerals, creatine, glutamine & MCT

Optimum Nutrition Serious Mass is the ultimate weight gain formula. Each delicious chocolate flavoured shake delivers 1,250 calories - with no added sugar and less than 5g of fat per serving. This includes 250g of carbohydrates, and 50g of blended protein to support muscle growth.


Mix 2 scoops with water or milk in a shaker, and enjoy between meals, post-workout and/or before bed. Supercharge your Serious Mass shake by adding nuts, fresh or frozen fruits or other ingredients.

Directions:

Add two heaped scoops of Serious Mass to a blender filled with 710 ml 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 710 ml of non-fat 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.

Rated 5 out of 5 by from 16-18 year old, 2 years using this product. I have been using this product since I turned 16, I began my work in the gym in the later period of 15 years old. I had trouble gaining mass due to my high metabolic rate, meaning I was unintentionally becoming more lean than building size. I started using this mass gainer after trialing some others and found this to be the most efficient and best tasting. After editing my diet, dedicated gymwork 5 days a week for two years and this products effects, I have grown from being 40kg at 15, to 90kg at 18 with a steady rate of progress. Summed up: Worth the money, I usually buy 2 tubs which can last 3 months with controlled use, haven't ran into any issues with this product and I feel it's the most efficient product for pure size gain. Tastes very nice, I store throughout my workday as powder and fill with water about an hour before the gym, although it can and will be effective mid or post workout. Definitely stronger using this. Note: My progress is due to my lifestyle, I set a lot of time aside for my gymwork so results may be worse if you don't correctly diet, or better if you do :). Cheers!
