Relentless Origin Ultra<br>Taste Rating: 4/5<br>Originality Score: 3/5<br>Caffeine: 32mg/100ml<br>Calories: 3 kCal/100ml<br>Purchased from: Asda<br>Considerably better than Relentless Origin. It doesn't suffer from that odd brewed taste of its full fat cousin, and is overall much more palatable. It's still a bit watery, and not the best Relentless in the range, but it is low in calories. Choose this over regular Origin.<br><br>#energydrink #energydrinks #Guarana #LargeCan #LowCalorie #UK
