Unfortunately the manufacturers of Banzai Energy Drink are not willing to disclose the levels of caffeine in their product.

Banzai Energy Drink has 3 flavors, one of which - Original - is available in a 16oz can. (The other flavors "Banzai-Blue" and "Sugar-Free-Banzai" are only available for on-tap distribution in clubs and bars).

Otherwise, Banzai is a fairly typical energy drink recipe that is said to have less corn-syrup flavor and caffeine-aftertaste than its competitors.
