Significant scientific studies now suggest what athletes have always known. Faster, more lasting muscular gains seem to occur when taking extra protein. Muscle growth is higher when protein intake is higher. Monster Mass™ is one of the most powerful, yet easily digestible, mass-building protein's. 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 one of the biggest blasts of multi-source sustained release proteins. 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). Monster Features: 50 Grams Multi-source Protein Matrix Completeness and balance to the extreme! Featuring whey concentrates, whey isolates, isolated milk protein, caseinates, lactoferrin, l-glutamine, glutamine peptides and free form bcaa's l-valine, l-leucine, l-isoleucine. 50 Grams Of Digestible Protein 250 mg of aminogen® (a patented bioenzyme proteolytic digestive system), bromelain, and papain ensure the breakdown of proteins into absorbable peptides. Monster Complex Carbohyrates Waxy maize starch and maltodextrin provide massive amounts of glucose energy to fuel muscle growth and recovery. These complex carbs trigger the insulin response necessary to really drive protein utilization and amino acid uptake. Leanlipids™ Plus Calorically dense sunflower and/or safflower oil, medium chain triglycerides, canola oil and conjugated linolenic acid (cla) are excellent sources of energy for muscle growth.
