Researchers concluded that: (1) the protective activity of L-arginine involves gastric hyperemia (blood flow increase) mediated by NO (nitric oxide) and a mild irritant effect due to enhanced generation of endogenous prostaglandins, and (2) the ulcer healing properties of L-arginine depend upon its hyperemic and angiogenic actions, possibly involving NO.

Nitric Oxide (NO) precursor. Used by athletes to promote hemodilation or ‘pump’ during workout. Involved in synthesis of nitric oxide from L-Arginine and nitric oxide synthase reaction.

NO2 Hemodilator
NO2 is a powerful nitric oxide generating, performance enhancing HEMODILATOR. In a double-blind clinical trial conducted at Baylor University, NO2 was shown to be both safe and effective for increasing strength and power while delaying the onset of muscle fatigue. Comparing results between the NO2 group and the placebo group, standard repeated-measures ANOVA statistical test analyses demonstrated that the NO2 group boosted their strength by more than 300%, increased sprint peak power, and delayed the onset of fatigue.
