PUMP XL is an advanced amino acid blend formulated for research focused on nitric oxide production, vasodilation, and nutrient transport. Each mL delivers a total of 450 mg of active compounds: L-Arginine (100 mg), L-Ornithine (100 mg), L-Citrulline (100 mg), L-Lysine (100 mg), and L-Glycine (50 mg). These amino acids are widely studied for their collective impact on vascular tone, endothelial function, and metabolic performance in vitro. Arginine and Citrulline are precursors in the nitric oxide synthesis pathway, while Ornithine is involved in the urea cycle and ammonia clearance. Lysine and Glycine contribute to protein synthesis and cellular repair.
