Our Nitric Oxide Booster Formula is perfect for those huge pumps we all seek. With ingredients like L-Arganine HCL, these massive pumps are possible. L-Arganine is an amino acid that helps make proteins and is necessary for the production of nitric oxide. Nitric Oxide is a signaling molecule that is required for a variety of bodily processes and functions including blood flow regulation, mitochondrial function(energy) and cellular communication. To achieve maximum muscular growth, your working muscle needs adequate blood flow to improve muscular efficiency of ATP production in the mitochondria (reducing the oxygen cost of exercise). The removal of ammonia and other metabolites through better blood flow allows athletes to recover more quickly and may result in better growth stimulus and adaptive growth response to micro-tears. Recommended dose is 2 capsules 30-60 minutes before exercise.
