Most powerful energy drink??

Question

Does anyone know what the most powerful energy drink on the market is? By powerful, I mean most milligrams of caffeine per serving. I saw one at the store today with 300 mg of caffeine per serving, and it was a two serving drink, so that means it was 600 mgs of caffeine per can. I can't recall the name of it though, but it was a short name, and it wasn't a traditional energy drink can.
