European regulations suggest a maximum of 32mg of caffeine per 100ml, so around 160mg for the whole 500ml can in this case. the vast majority of energy drinks from Europe sticks to this 32mg per 100ml. There are some energy drinks that have more caffeine, but those are quite rare.
Have you ever tried one of these?
Is low caffeine count common for European cans? It'd be hard to find an energy drink here (US) under like 90mg of caffeine
