Product Info

  • The ultimate in weight gain formulas
  • Each delicious strawberry flavour shake contains 1,250 calories per serving
  • 50g of blended protein and 250g carbs per serving - with no added sugar
  • Includes 25 vitamins and minerals, creatine, glutamine and MCT

Optimum Nutrition Serious Mass is the ULTIMATE weight gain formula. Each great tasting strawberry 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.


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 3 out of 5 by from Too sweet Currently using this flavour and it isn’t the best to say the least the strawberry flavour is too sweet

Rated 4 out of 5 by from Does what it says! Purchased this on behalf of my son who wanted to bulk up a bit.....he found this gave him a good recovery & energy level but found the taste rather bland. Much better when blended with fresh strawberries or banana. Good value as bought in penny sale but wouldn't spend so much otherwise.

Rated 1 out of 5 by from Over priced even when on offer! This flavour is way too sweet and very sickly which makes you not want to finish the tub. Hard to mix unless you like it lumpy and enjoy the extremely powdery taste it leaves in your mouth, I found that I had to drink at least 500ml of water after drinking this stuff to wash/rinse my mouth out to stop the overly sweet, sticky feeling that it left!
