Why Caffeine Bullet?
Because it's chewed rather than swallowed, Caffeine Bullet kicks 3x faster than drinks, powders, or tablets.
Plus, by isolating your caffeine from your carb or electrolyte intake, Caffeine Bullet lets you unlock the performance-enhancing benefits of caffeine without having to alter your overall nutrition plan.
