We like 5-Hour Energy because in a single two-ounce energy “shot” you get the jolt of an energy drink without having to slug down sixteen ounces to get there. Since its launch in 2004, 5-Hour Energy's ubiquitous red bottles seem to have popped up in every gas station and convenience store across the country. Each shot contains a blend of taurine and B-vitamins infused with as much caffeine “as a cup of premium coffee.” Although 5-Hour Energy now comes in several flavors, the original is often described as berry-flavored cough syrup. The drink’s claim that it produces “no crash later” caused it to be reviewed by the National Advertising Division in 2007. The fine print on the label now reads that “no crash” actually means “no sugar crash.” Despite this controversy, 5-Hour Energy has generated over $1 billion in retail sales and spawned a host of imitations.
