THESE WORK! My favorite flavor is the blueberry acai! These are the best and probably healthiest energy shots out there. The ingredients are super clean. I thought I could finish a bottle in one sitting but I was wrong. After a few sips halfway with one bottle, I feel myself wide awake and energized as if I just drank some coffee. One shot / bottle lasts me for 2 days or mornings. Try it out yourself!
