This is the Sugar Free variety of the Relentless franchise. Instead of just marketing it as a low calorie version they’ve given it its very own name, and for good reason I might add. It isn’t just a de-sugared version of Origin, it is a whole new flavour. The bitterness of Origin is missing, but you can still tell that it is part of the Relentless brand. It tastes slightly watery compared to other energy drinks, but that’s not necessarily a bad thing as this is what stops it being too sickly or too sweet.
The balance is just right in this product and although it’s not the best flavour out there, it manages what I would consider a well deserved middle ground: decent kick, sugar free, no bad aftertaste, and a flavour that should be acceptable to most.Relentless Libertus (Sugar Free),
