– Next time you’re tired and hungry, don’t waste time pounding a Red Bull and a snack—get both fixes with some Perky Jerky. Available on the Internet and coming next week to Sports Authority outlets in New York, each ounce packs as much caffeine as one cup of coffee or a can of Red Bull. “This is a great combination,” a company founder tells the Daily News, “like vodka and orange juice, or peanut butter and chocolate.” Matt Keiser says the idea was born on a Utah ski slope 4 years ago, when he slopped Red Bull on some jerky. It got mixed person-on-the-street reviews, however. “It is disgusting,” one New Yorker says. “I like beef jerky. I like caffeine. But it is not a good combination.” But, says another, “I didn’t crash after the workout like I do with Red Bull.”
