The FDA is raising hackles over the equivalent of an espresso shot in a bottle: the popular 5-Hour Energy drink that has billions of dollars in sales over the past decade.

The hubbub over 5-Hour Energy, which has some fans stockpiling 12-packs of the bottles in anticipation of a possible ban, was sparked by an article in the New York Times claiming that 5-Hour Energy has been “linked” to 13 deaths reported to the FDA in the past four years.
