Can't get enough of this stuff! Highly effective and keeping me alert and awake, and I find it delicious. And in this 12-pack, it's far more affordably priced than what you find in the gas station. Plus, those concerned that this is simply the packaging of dangerous chemicals as an unethical cash-grab would do well to look up Manoj Bhargava, the founder of the company — and the documentary "Billions in Change," which documents his use of the proceeds from 5-Hour Energy to literally solve the planet's most pressing and universal problems. This man is not the stereotypical "money above all else" businessman, and the sales of the product are making far more difference than most of its customers realize.
I'm no scientist, but I think the ingredients are basically water, caffeine and amino acids. (At least that's what I tell myself. Glug glug.)
Other Ingredients: Water Purified, Natural & Artificial Flavors, Potassium Sorbate, Sodium Benzoate, EDTA (Ethylenediamine-Tetra-Acetic Acid) (to protect freshness), Sucralose
