The Active Ingredient Is: Arginine Nitrate

Arginine Nitrate is a nitric oxide boosting compound used to support blood flow to working muscles and enhance pump quality. This form combines the amino acid arginine with nitrate to promote nitric oxide production.

This ingredient works alongside other components in the formula to aid vascular function and nutrient delivery during training, contributing to a supportive muscular outcome without stimulant use.

What Does Arginine Nitrate Do?

Arginine Nitrate helps to increase nitric oxide levels, which supports vasodilation and improved blood flow to muscles during exercise. This mechanism can play a role in nutrient delivery and endurance in resistance training contexts.

Overall, the combination of this ingredient with other absorption and hydration support helps normal physiological processes related to blood flow and muscle performance during activity.
