The Primary Active Ingredient Here Is: Caffeine Anhydrous

Caffeine is a central nervous system stimulant that helps with alertness and mental sharpness during activity.

This formula also includes other ingredients such as L-Citrulline and Beta-Alanine to boost energy and endurance during performance, together with Taurine and L-Tyrosine for focus and fatigue management.

What Does Caffeine Anhydrous Do?

Caffeine helps sustain alertness and supports high-intensity exercise performance by influencing perceived effort, as described in clinical research.

Dr. Spriet of the University of Guelph found that caffeine can significantly improve muscular strength and endurance and perceived exertion during exercise, aligning with EFSA guidance on central nervous system stimulation and performance.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
