If you’re looking for a Nitric Oxide product, do not get one that contains arginine. Arginine does NOTHING to increase nitrate levels in the blood. Arginine NO supplements are a complete hoax, scam, sham, however you want to put it. If you want a good NO supplement I would get something fruit based or super fruit based, like a beet powder, spinach powder, or grape concentrate. These have been shown to help out with nitrate levels in the blood which will give you a better pump.
This supplement was first sold as male enhancement. Then it went to weight loss and bodybuilding. It’s likely found its way to the kitchen sink by now. This is the biggest scam in supplement history. Sad, but true. Here’s the first study showing L-Arginine Doesn’t work. Its really compelling and you have to read it
No effect of short-term arginine supplementation on nitric oxide production, metabolism and performance in intermittent exercise in athletes.

Arginine supplementation has been shown to alleviate endothelial dysfunction and improve exercise performance through increasing nitric oxide production in patients with cardiopulmonary diseases. In addition, arginine supplementation could decrease accumulations of lactate and ammonia, metabolites involved in development of muscular fatigue. The aim of this study was to investigate the effect of short-term arginine supplementation on performance in intermittent anaerobic exercise and the underlying mechanism in well-trained male athletes. Ten elite male college judo athletes participated with a randomized crossover, placebocontrolled design. The subjects consumed 6 g/day arginine (ARG trial) or placebo (CON trial) for 3 days then performed an intermittent anaerobic exercise test on a cycle ergometer. Blood samples were collected before supplementation, before and during exercise and 0, 3, 6, 10, 30 and 60 min after exercise. ARG trial had significantly higher arginine concentrations than CON trial at the same time point before, during and after exercise. In both trials, nitrate and nitrite concentration was significantly higher during and 6 min after exercise comparing to the basal concentration. The increase in nitrate and nitrite concentration during exercise in both trials was parallel to the increase in plasma citrulline concentrations. There was no significant difference be – tween the 2 trials in plasma nitrate and ni – trite, lactate and ammonia concentrations and peak and average power in the exercise. The results of this study suggested that short-term arginine supplementation had no effect on nitric oxide production, lactate and ammonia metabolism and performance in intermittent anaerobic exercise in welltrained male athletes.
The second study: Here is complete proof that the three best selling nitric oxide supplements do not do a damn thing for raising nitrate levels in the blood.
Comparison of pre-workout nitric oxide stimulating dietary supplements on skeletal muscle oxygen saturation, blood nitrate/ni – trite, lipid peroxidation, and upper body exer – cise performance in resistance trained men
the tested finished products are clearly ineffective in terms of increasing blood flow and improving acute upper body exercise performance, and do not produce results that match the widely advertised marketing claims. These concluding statements should be considered within the context of the current study design, and may not be generalized to other designs inclusive of different exercise modes and intensities, and/or different outcome measures.
