Rockstar Zero Carb  is a sugar free energy drink from Rockstar Energy, but with more caffeine than the original sugar free version. 

Rockstar makes 25 different energy drinks including  Rockstar Juiced, Rockstar Roasted, and Super Sours.

The Zero Carb version, however, has one of the highest concentrations of caffeine found in an energy drink. The cans come in 16 fluid ounces, with 1000mg of Taurine, 120mg of caffeine and 100mg of Green Tea extract per 8 ounce serving.

Rockstar Zero Carb is suitable for healthy adults only who are aware of their sensitivity to caffeine. 

The Australia version only has 160mg of caffeine/500ml can.
