Mountain Dew Amp

Mountain Dew Amp (or simply Amp) is an energy drink brand produced by PepsiCo. At the time of its introduction in 2001, Amp Energy was initially distributed under the Mountain Dew soft drink brand. Beginning in 2009, it was produced and labeled under its own stand-alone trademark name, but in 2018, reverted to using Mountain Dew branding. The beverage is packaged in both cans of 16 and 24 US fluid ounces (473 and 710 mL), and is sold in the United States, Canada, the United Kingdom and Lebanon. In 2009, Amp Energy was the number four energy drink brand in the U.S. in terms of overall retail sales.
