Relentless Zero<br>Taste Rating: 4/5<br>Originality Score: 3/5<br>Caffeine: 32mg/100ml<br>Calories: 3 kCal/100ml<br>Purchased from: Asda<br>Relentless energy drinks have had a bit of a design overhaul recently. Gone is the gothic-style line art graphics on the can, and in are loud and bold colours. With that rebranding has come the new Relentless Zero, which is effectively a renamed version of their awkwardly named Relentless Origin Ultra (maybe because it's easier to understand a 'zero' drink will be low calories instead of the wholly non-descriptive 'ultra' moniker they used previously. The drink is the same as before so far as I can tell - slightly watery but no strange brewed taste.<br><br>#energydrink #energydrinks #Clone #Guarana #LargeCan #LowCalorie #UK
