The Active Ingredient Is: Caffeine (Anhydrous). Caffeine is a central nervous system stimulant that many of us reach for to help with energy and focus when we’re moving. This version comes as caffeine anhydrous to give a quick, steady lift for your workouts.

Caffeine helps with wakefulness and keeping up mental and physical stamina, a mechanism that a lot of sports nutrition guides mention.

What Does Caffeine Do?

Dr Grgic from the University of Zagreb found caffeine can boost focus and endurance during sport performance, which matches EFSA recognised uses for lifting exercise output.

This product also has ingredients like L-citrulline malate, beta-alanine and L-theanine, which help with the overall energy, focus and endurance profile described here in the formulation.
