Bulk-Up Weight Gainer Vanilla
Brand: Tapout Sports Nutrition
Dr. Feb's Analysis
Scientific Mechanism
At the cellular level, Maltodextrin and Fructose rapidly replenish glycogen stores, spiking insulin to drive nutrients into muscle cells. The Canola Oil, Safflower Oil, and Medium-Chain Triglycerides provide dense caloric energy via beta-oxidation. Crucially, the Bulk-Up(TM) proprietary blend delivers essential amino acids like L-Leucine (3,305 mg). L-Leucine activates the mTOR pathway, a master regulator of protein synthesis, signaling the body to repair and build new muscle tissue.
