L-THEANINE: An amino acid used by the body for increased dopamine regulation. When taken in conjunction with caffeine it demonstrates heaps of athletic benefits:
⩥ Increases reaction time, attention, and memory
⩥ Reduces jitters in caffeine-sensitive individuals
⩥ Reduces stress and causes relaxation without affecting attention and energy

CAFFEINE ANHYDROUS: Caffeine together with the other focus-enhancing ingredients in Prefix is clinically proven to reduce any feelings of effort. Caffeine has been found and confirmed to:
⩥ Significantly increase repetitions and readiness to invest effort in athletes
⩥ Increase focus and energy

CHOLINE BITARTRATE: Choline supplementation supports intense training by maintaining acetylcholine levels for neural signalling and participating in the BMHT pathway to convert homocysteine to methionine during prolonged sessions.

BETAINE ANHYDROUS: Clinical trials suggest that betaine supplementation triggers a significant muscle growth response. Betaine supplementation has also been shown to:
⩥ Reduce fatigue when taken during training and exercise times
⩥ Increases total repetitions and volume versus placebo
⩥ Improve phosphocreatine replenishment between sets when creatine is taken daily
Another study has shown that betaine was found to increase HGH and IGF-1 and decrease cortisol in healthy bodybuilding men.

TAURINE: Taurine is a must-have amino acid in any pre-workout formula that contains beta-alanine. Taurine competitively interacts with beta-alanine; thus, supplementation with beta-alanine without taurine can lead to states of Taurine deficiency. Taurine has also been found to be effective in combatting DOMS.

L-Citruline: Citrulline malate is the "Holy Grail" of current pre-workout science. It has been found to:
⩥ Improve strength, aerobic performance, and muscle endurance
⩥ Be at least twice as effective as L-arginine supplementation at raising nitric oxide
⩥ Enhance the use of branch chain amino acids like leucine during exercise

BETA-ALANINE: Beta-alanine has been shown to increase intracellular muscle carnosine levels, which are quickly depleted during intense exercise. Supplementing with proper amounts of pure Beta-Alanine as found in Prefix, is shown to:
⩥ Delay the onset of neuromuscular fatigue in men and women during intense exercise
⩥ Promote the formation of healthy proteins
⩥ Increase lean mass and decrease fat in wrestlers
