XXL PUMP is a comprehensive amino acid complex formulated for research on nitric oxide production, cellular volumization, and metabolic performance. Each milliliter contains L-Arginine (100 mg), L-Citrulline (100 mg), L-Ornithine (100 mg), L-Glutamine (100 mg), L-Glycine (50 mg), L-Lysine (50 mg), Taurine (50 mg), and BCAA 2:1:1 (5 mg), totaling 655 mg of active compounds per mL. This blend is commonly used in in vitro research to study vascular endothelial function, ammonia clearance, amino acid-driven mTOR signaling, and metabolic regulation. L-Arginine and L-Citrulline are particularly investigated for their effects on nitric oxide pathways, while L-Ornithine supports studies of urea cycle function and detoxification processes.

For in‑vitro laboratory research only. Not a drug, food, cosmetic, or veterinary product. Not for human or animal administration.
