Pre-workout for energy and focus containing proven performance enhancers

L-Citrulline is an amino acid precursor that plays a major role in nitric oxide production. An increase in nitric oxide overall improves muscle performance by reducing fatigue and improving endurance for both aerobic and anaerobic exercise.

Beta alanine is a building block for carnitine, a molecule which has been shown to buffer the build-up of lactic acid within the working muscles and therefore giving you the ability to train harder and longer past the point of fatigue. Beta alanine supplementation has also been shown to positively benefit high intensity cardiovascular performance such as sprinting.

Caffeine is the most common stimulant found within any pre-workout supplement on the market today. Its stimulatory effects on the brain have been shown to improve alertness, focus, concentration and overall mental state giving you the ability to stay on track and focussed on the workout ahead. Not only that, caffeine has also been shown to benefit fat loss and inhibit muscle breakdown.
