Nutrex NIOX

Nitric Oxide Booster for Pump, Endurance and Muscle Growth

NIOX is an advanced Nitric Oxide boosting muscle and pump formula. The liquid capsules help for fast absorption to quickly increase nitric oxide in the bloodstream. With intense training, NIOX helps to get more blood, nutrients and oxygen into the muscles. This generates a bigger pump effect for fuller muscles.

Many weightlifters believe that a great pump-effect is imperative in faster muscle growth. Optimum results are achieved when NIOX is taken daily.

Take 3 liquid capsules with 10 oz. of water 30 minutes before breakfast and repeat 30 minutes before dinner. On training days, take one of your servings 30 minutes before you work out. For optimum results stay hydrated.
