Bang has the most caffeine of the three at 300mg per 16 oz can, Ghost Energy sits in the middle at 200mg, and C4 Energy has the least at 200mg. The servings are identical, so the per-can numbers settle it outright: a 100mg spread from top to bottom.

What a 100mg spread actually feels like
All three come in the same 16 oz can, so the gap is the whole difference. 100mg is roughly 1.1 cups of brewed coffee, which is the easiest way to size it if you already know your coffee tolerance. Switching from C4 Energy to Bang once a day changes your weekly intake by about 700mg.
The three head-to-head pages
Each pairing has its own page with the full math:
- Bang vs Ghost Energy, head to head
- Bang vs C4 Energy, head to head
- Ghost Energy vs C4 Energy, head to head
Which one should you pick?
Take C4 Energy when you want the smallest dose of the three, Ghost Energy when you want a middle number without thinking about it, and Bang when you actually want the 300mg and know how you handle it. If you drink more than one caffeinated thing a day, the useful move is adding the day up against the 400mg reference rather than judging each drink alone.
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.
