Nutrabolt C4 Performance Energy carries 160 mg of caffeine in a 500 ml can (17 fl oz), or 32 mg per 100 ml. The catalogue median is 30 mg per 100 ml.
There is no sugar in this can. Sweeteners carry the taste, which is what keeps it at 20 kcal instead of the 100-plus kcal of a typical sugared can.
It matches Dark Dog Original milligram for milligram at 32 mg per 100 ml — so the two separate on sugar and calories, not on the stimulant.
On sugar the heaviest can in the catalogue is Burn Energy Drink (500 ml), at 15.0 g per 100 ml — a useful marker when reading the figure above.
