Nutrex L-Arginine 1000 120 Tablets

Arginine is the direct precursor your body converts into nitric oxide, the signal that widens blood vessels. Wider vessels mean more blood reaching working muscle, which is both the pump you can see and the oxygen and nutrient delivery you cannot.

Nutrex keep this one deliberately plain: 1,000mg of L-arginine HCl per tablet and no stimulants at all. That is what makes it flexible. You can stack it with a pre-workout without adding to your caffeine load, take it on a rest day for circulatory support, or use it in the evening when a stimulant is the last thing you want. Better circulation also means waste clears faster from muscle tissue between sets.

The bottle holds 120 Tablets.
