Ingredients Breakdown

L-Citrulline - This ingredient is a pump inducer, that works as a vasodilator. Citrulline increases Arginine levels in the body, which causes blood vessels to dilate therefore increasing blood flow.

Beta-Alanine  - is used at the typical 3,200mg dose. This ingredient is used to increase workout endurance.

L-Tyrosine - is an amino acid that aids in mental focus. We often times see this product used in nootropic supplements and even pre-workouts for this particular reason.

Citicoline - is a brain nutrient that supports mental energy, focus, attention, and overall cognitive health.

Caffeine Anhydrous - is used at 350mg, which is a solid dose for a high stim pre. This will definitely give you some quick energy and fuel you enough to get through a tough workout. With the Caffeine Anhydrous dose being so high, it could cause a crash soon after it has hit peak blood levels in your body, however....

ZumXR™ - is a timed-released Caffeine. This will help prevent the post workout crash.

ViNitrox - consists of grape and apple polyphenols. Supplementing with VitNitrox leads to increased maximum performance and exercise capacity. The longer you can go, the more the blood can flow. 

ElevATP™ - is a blend of ancient peat and apple polyphenols that has been clinically shown to increase endogenous levels of ATP. Increasing ATP levels leads to an increase in strength, power and overall performance. 

Huperzine A - This is an ingredient that can lead to an improvement in metal focus.
