SIS Go Caffeine Shot Cola Taste Rating: 2/5 Originality Score: 3/5 Caffeine: 250mg/100ml Calories: 15 kCal/100ml Purchased from: Sainsbury's
This drink was so sour that I didn't get any cola flavour at all. I might just as well have been sucking on a lemon to be honest. Still, it's a very fast acting and potent drink which bolted me awake pretty quickly!
