The Active Ingredient Is: L-Citrulline

L-Citrulline is an amino acid that helps to support nitric oxide production, aiding normal blood flow and vascular function. It comes as a pure, free-form powder to help delivery and absorption within this blend.

This version is supplied as 100% pure L-Citrulline powder chosen for high bioavailability and synergistic use with other non-stimulant ingredients in the formula.

What Does L-Citrulline Do?

L-Citrulline helps to support nitric oxide production, which can boost blood flow and exercise performance during high-volume training, contributing to improved muscle pumps and endurance.

Scientific evidence indicates that L-Citrulline at effective doses helps increase NO availability and better training performance, helping to maintain pump quality and reduce fatigue during workouts.
