45 Grams of Mass-Generating Protein. Growth • Power • Strength. 600 Massive Calories Feed High Metabolisms. 45 Grams of Protein Fuels Muscle Growth. Over 56 Grams of Muscle Fueling Amino Acids. 60 Grams of Glycogen Replenishing Carbohydrates. Premium Lipids for Energy and Muscle Growth. A Complete Mass-Gaining Advantage. Prolab® N-Large2™ provides a complete mass-gaining advantage to hard gainers and athletes looking to build serious muscle. The carefully selected blend of proteins carbohydrates and lipids stack up to yield 600 muscle-building calories per serving to help even the hardest gainers to build muscle. . With 45 massive grams of muscle building proteins PROLAB N-Large-3 feeds gains in 3 stages. First Whey Isolate begins to absorb immediately - quickly igniting muscle-repairing protein synthesis. Second Whey Concentrate supports the rebuilding momentum. Third Micellar Casein digests slowly over time providing the extended amino acid flow muscles crave for building dense new muscle fibers. PROLAB N-Large-3 provides long lasting energy for growing muscles with slow burning complex carbohydrates and energy-rich lipids from Medium Chain Triglycerides (MCTs) and Safflower oil. MCTs help to preserve stored glycogen and amino acids from being pulled from lean muscle tissue sparing hard earned growth.
