Robust Energy Drink was first launched in the UK in 2008, but is now available throughout most regions of the USA as well.

This drink is marketed as a cheaper alternative to Red Bull and the ingredients as well as the flavors would certainly agree since Robust seems to be a pretty accurate clone.

Robust has just slightly less caffeine than Red Bull.
