Note: Consumer Reports recently tested Monster and found it to have, on average, 184mg per 16 fl.oz. can. This is slightly more than what Monster states, which we have listed above.

Many of the Monster drinks have the same caffeine content per ounce, but some are slightly higher due to the same energy blend being used in drinks with less volume.

The caffeine content is less per ounce in countries with stricter caffeine laws such as Australia and New Zealand. 

Monster Energy has a similar marketing plan to that of their biggest rival Red Bull. They sponsor huge extreme sporting events as well as individuals in each sport. Also, you will see them promoted at music festivals around the world.
