It was the first 5-hour ENERGY® shot flavor. And many years later, it’s still one of the most popular in the lineup. Why? Because it tastes great? That’s part of it. Because it’s super portable? Definitely important. Because it just plain works? That’s the big one. Boasting a blend of B vitamins, nutrients and caffeine, the delicious Berry Flavor Regular Strength 5-hour ENERGY shot started it all in 2004.
