                                According to product information and nutritional charts, a standard 1.93-ounce shot of 5-hour ENERGY contains 200 mg of caffeine, whereas a 16-ounce can of Original Monster contains 160 mg. This means that while Monster has a larger total volume, a single serving of 5-hour ENERGY packs a more concentrated punch of caffeine.
