GU Jet Blackberry

As any berry connoisseur knows, the taste of a blackberry varies throughout the season. The taste of Jet Blackberry is like that mid-summer berry: ripe enough to deliver unmatched sweetness while still bringing out a touch of tart. It won&&';;t make your mouth pucker, but it keeps things interesting. This flavor also packs 40mg of caffeine - to help you turn on the jets, of course.
