Perky Jerky is a brand of PEMS, LLC based out of Englewood, CO. It launched officially just last month.
It's claimed to be a "performance enhancing meat snack", being infused with guarana and caffeine, two popular energy supplements used in a variety of other products designed to invigorate one's body. The company says one package of Perky Jerky contains about the same caffeine as a can of energy drink.
As the story goes, the creators of this jerky were at a ski lodge, preparing for a day of skiing, when by accident some energy drink spilled into their bag of peppered beef jerky. They ate it anyways, and found it still tasted just as good as before, but a little more tender, and seemingly kept them sliding the down the slopes all day long.
