Do you remember, when you were a kid, having a grape ice-pop on a hot summer day? That simple, sweet, lip-smacking taste has grown up and now includes caffeine-enhanced energy. All the yummy goodness you remember without the sticky fingers or purple stained t-shirt. This GoSip Concentrated Flavor Cartridge is enhanced with energy and contains zero sugar, zero calories, is dairy-free, and has no artificial flavors or colors.
