If L-arginine is ineffective at generating nitric oxide, why is it in the PUMP-BOL formula?
That’s a great question, and we are glad you asked. By now it is no secret that L-arginine is incapable of boosting nitric oxide levels in healthy humans. While an arginine deficiency can hinder NO production and endothelial function, it can also prevent nitrate tolerance in humans(26). Tolerance to nitrates, as with stimulants, can develop with continued use over time. This allows PUMP-BOL to work just as good four months from now as it does today.
