Serious weight gain goals require serious measures. To gain just one pound of bodyweight, it takes approximately 3,500 calories above and beyond what is needed for daily maintenance. However, individuals with high metabolisms often find it difficult to consume enough whole foods to achieve this level of caloric intake. What’s more, preparing high-calorie whole food meals isn’t always as convenient or easy as blending a nutrient-dense shake.

Each great-tasting and convenient serving of Serilous Mass provides:

  • 1250 calories from high-quality, energy rich sources.
  • 50 grams of protein from a combination of fast and slow digesting sources including whey, casein, and egg.
  • 254 grams of carbohydrates-with no added sugar- to support fueling of intense workouts and aid in the replenishment of glycogen stores.
  • Enhanced with Creatine, Glutamine, and intense physical activity, Serious Mass offers an ideal, convenient solution to these often encountered weight-gain hurdles, helping to support your quest for a massive, powerful physique.
