| Celsius | Bang | |
|---|---|---|
| Caffeine per serving | 200mg per 12 oz can | 300mg per 16 oz can |

Which one should you pick?
Pick Celsius when you want the lighter dose or a slower ramp, and Bang when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
