Product Information

📋 Directions for Use

DIRECTIONS Take MONSTER MASS anytime you would enjoy a shake or gainer, but want a better tasting, more anabolic formula. Mix four scoops in 18-20 fl. oz. water. BEFORE WORKOUTS To help fuel your workout, use MONSTER MASS 45-60 minutes prior. AFTER WORKOUTS 15-30 minutes after workouts your body’s growth window is open, use MONSTER MASS at this time to maximize the benifits of your workout. PRIOR TO BED Sleep is actually a catabolic period. Use MONSTER MASS before bed to wake up more anabolic.

⚠️ Warnings & Precautions

ALLERGEN STATEMENT: THIS PRODUCT CONTAINS INGREDIENTS DERIVED FROM MILK AND SOY. This product is manufactured in a facility that processes milk, soy, wheat and eggs.

🧪 Formulation Notes

SUPER EASY TO DIGEST: Our strategic use of Aminogen(R) (Patented Bio- Active Polypeptide Enzyme System), bromelain, papain and lactase ensures extreme ease of digestion. Thee enzymes ensure the protins 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 digest. While MONSTERMASS may be the most powerful mass building protein in the world, it’s still easy on your stomach.

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(R) (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(TM) 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.

Additional Information

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 system makes it the ultimate nutritional tool. When combined with high intensity weight training it helps you build monster size muscle. FAST & SLOW PROTEINS: MONSTER MASS delivers the biggest blast of multi-source sustained release in history. Rapidreleasing 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 create the optimum anabolic window that lasts for hours.

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).

THIS STUFF REALLY IS MONSTER. DO NOT USE WITH CAUTION. BE A MONSTER.
