Optimum Serious Mass

Serious weight gain requires serious calories. However, those who need the extra calories most, often have the toughest time consuming enough of them. For many aspiring to be bigger, highly-active metabolisms, weaker appetites and on-the-run lifestyles make consuming sufficient calories through whole foods alone a real challenge. With Serious Mass, you've got nothing to lose and lots to gain.

Serious Mass Features:

  • Adding Calories has Never Been this Easy or Tasted So Good
  • 1,250 High Quality Calories per Serve
  • 50g of Blended Protein
  • Over 250g of Carbohydrates with NO ADDED SUGAR
  • Enhanced with Creatine and Amino Acids
  • 25 Vitamins and Essential Minerals

We've consolidated over 1,250 calories, 50 grams of protein, 250-plus grams of carbohydrates, and 25 vitamins & minerals with added aminos and creatine into every serving. Serious Mass provides you with the tools you need to pack on the pounds and - when coupled with serious weight room effort – develop your physique to the fullest. It's time to stop thinking small; get serious - Serious Mass!*
