Mass-Building Protein! 600+ Calorie Advanced Protein!


MONSTER MASS is the most powerful, yet easily digestible, mass-building protein in history. Although it tastes like an ultra-rich milk shake, MONSTER MASS’s 600+ calorie advanced protein and carbohydrate systems make it the ultimate nutritional tool for building monster size and muscle.

Fast & Slow Proteins:

MONSTER MASS delivers the biggest blast of multi-source sustained release proteins in history. Rapid-releasing anabolic whey, glutamine peptides and free form BCAA’s are complemented by slower, anti-catabolic caseins and other complete milk protein isolates. This powerful combination of fast and slow proteins creates an “anabolic window” that lasts for hours.

Super Easy To Digest:

Our strategic use of Aminogen (Patented Bio-Active Polypeptide Enzyme System), bromelain, papain, and lactase ensures extreme ease of digestion. These enzymes ensure the proteins in MONSTER MASS are delivered as free-form amino acids and small peptide chains to ensure maximum uptake and absorption. Plus MONSTER MASS is 98% lactose free, making it even easier to process. While MONSTER MASS may be the most powerful mass building protein in the world, it’s still easy on your stomach.

Boost Your Nitrogen Balance:

MONSTER MASS helps create positive nitrogen balance, the gold standard of anabolic potential. MONSTER MASS provides high levels of essential amino acids to bathe muscle fibers in an “anabolic soup” to stimulate protein synthesis and muscle growth (hypertrophy).

  1. Quality
    Monster mass
    Tastes great for the money!
  2. Quality
    Great taste
    I usually take monster massive first thing in the morning when I wake up to get feed my muscles after sleeping. I would suggest a different mass protein powder for psot-workout because this does not have much sugar. But the taste (chocolate) is probably my favorite all the powders I have ever taken.
