Love multiple flavors! Dissolves smoothly tastes great. What more can you want? Just wish they had a non caffeinated version in the same flavors

Taste is 10/10, I needed something for my afternoon slump, and I hate energy drinks. This was a perfect solution. Purchasing my 2nd canister today!

I use this product as a pre workout for my early morning workouts. It gives me the safe energy I need to power through my workouts.

This is my go-to energy drink. Coffee makes me sick, I have a plethora of sensitivities to foods. I finally found an energy drink that I can use for workouts and any during the day when I need an extra boost of energy that doesn't make me sick.
