MHP brings the most advanced mass-packing technology to your nutrition program with Up Your MASS. The result of over 10 years of research and development, Up Your MASS is so powerful, it can pack 16 lbs. of muscle onto the frame of the hardest gainer in just 5 weeks! The superior quality and quantities of muscle building nutrients in Up Your MASS far outweigh those used in competitor weight gain formulas-you will never find another weight gainer that works as quickly and effectively as Up Your MASS!45/35/20 Macrobolic Nutrition Ratio Creates the Perfect Metabolic and Hormonal Environment for Maximum Mass, Strength, Endurance and Recovery.Probolic Protein: The most advanced protein matrix ever developed, PROBOLIC protein (Supro soy protein isolate, whey concentrate, casein) feeds your muscles for up to 8 hours. The sustained release profile provides a quick, medium and slow release of muscle building amino acids for both fast and long-term nitrogen retention. PROBOLIC is loaded with mega amounts of Glutamine, Leucine, Branched Chain Amino Acids (BCAAs) and Nitric Oxide boosting Arginine in every serving-all of which are critical for muscle building, strength and recovery from workouts.Mass Load Carbs: The type and quality of carbohydrates used in any weight gainer will determine the type and quality of mass you pack on. Only Up Your MASS contains MASS Load, a unique agglomerate of carbohydrates (barley, oats and oat fiber) that optimizes the anabolic effect of insulin, allowing your body to build dense, high quality muscle mass. The advanced MASS Load carb blend also gives you sustained energy, fast glycogen replenishment and stabilized blood sugar levels. Unlike the competition, Up Your MASS is NOT loaded with maltodextrin and sugars (dextrose, sucrose) that can increase fat stores.Lipid Complex: EFA's in Up Your MASS stabilize insulin release and improve nitrogen retention by slowing down carbohydrate and protein digestion. Both are key factors in building muscle quickly. Medium Chain Triglycerides (MCTs) provide an excellent source of energy and help preserve muscle glycogen, while clinically proven CLA is added to further increase lean mass.Amino Acid Profile (with 2 servings mixed with Whole Milk)Alanine 4,877mg, Arginine 7,105mg, Asparatic Acid 12,245 mg, Cysteine 1,397 mg, Glutamine 26,477 mg, Glycine 4,245 mg, Histidine 3,165 mg, Isoleucine 7,005 mg, Leucine 9,521 mg, Lysine 6,921 mg, Methionine 2,085 mg, Phenylalanine 5,769 mg, Proline 8,269 mg, Serine 5,637 mg, Threonine 4,989 mg, Tryptophan 1,925 mg, Tyrosine 5,017 mg, Valine 7,345 mg.
