Serious weight gain requires serious calories. Optimum Nutrition Serious Mass is the ultimate weight gain formula.

  • For muscle building and weight gain
  • More than 1260 kcal per serving to help boost your calorie intake
  • 50g protein per serving
  • 25 vitamins & supplements

Those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, Serious Mass is the ultimate in weight gain formulas. With over 1,250 calories per serving to boost daily calorie intake, 50g high protein to support muscle growth and repair, over 250g carbohydrates, and now with 3g of added creatine per serving to support performance, you’ve got nothing to lose and lots to gain. It is time to stop thinking small and get serious – SERIOUS MASS.

Use anytime, it is quick, convenient and easy to prepare. Serious Mass is ideal between meals, after weight training as part of your recovery routine and before bed. Just mix two scoops of Serious Mass (330g) with 710ml of water to create a tasty, calorie-packed shake.

Remember to:

We go to great efforts to ensure that the information on this page is accurate at the time that the page was last edited. As we are constantly reviewing and developing our products to meet our consumer needs, consumers, particularly those that suffer from allergies and intolerances, should always check product labelling, warnings, and directions provided with the product that is delivered, prior to use or consumption.

Directions:

Add 2 heaped scoops (330 g) 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. TIP: New users may find it beneficial to begin with ½ a serving daily for the first week and then gradually increase to 1 or more full servings several times a day.
