Good to know
- Caffeine figures are as published by Chowhound (25 April 2026) and The Takeout (15 June 2026). They are the brands' label figures, not lab tests.
- Wired X344 tops the list but had no new multi-packs on eBay when we checked, so it has no card here. Rockstar Xdurance (300 mg per Chowhound) is in the same position.
- Chowhound cites the FDA: no more than 400 mg a day for most healthy adults, and a toxic level of 1,200 mg in a short period. People on medication that interacts with caffeine should be more careful.
- Reddit popularity: the r/energydrinks all-nighter thread had 51 upvotes and 111 comments when scout read it on 2026-11-11.
