As if hot sauces aren’t quite spicy enough. DoubleKick Caffeinated Hot Sauce, which we found on ThinkGeek, purports to combine the best of Asian and Southwestern chili sauces before leveling up with ginger and caffeine. How much caffeine does it have really? Well, every serving of 1 tsp serves up 12 mg. Of course, there’s no stopping you if you want to gulp down the entire bottle at one go: that will be 672 mg of caffeine. Good luck catching some sleep.
