Overview
Cirkul's GoSip cartridge pairs caffeine with zero calories, sold six to a pack and made to click into a Cirkul bottle cap rather than double as a standalone mix. It gives existing Cirkul owners a caffeinated option alongside the electrolyte focused FitSip.
Where FitSip in the same Cirkul lineup targets electrolytes, GoSip targets an energy boost, giving existing Cirkul owners a caffeinated option to swap into their rotation. Every cartridge depends on the brand's proprietary cap and Flavor Dial, so it functions purely as a refill rather than a drink you could carry and use elsewhere.
- 6 cartridges per pack
- Caffeine enhanced, zero calories
- Works only with Cirkul sip bottles
- No added sugar or artificial colors
Who it's for
Fits people who already carry a Cirkul bottle and want a caffeinated, sugar free pick me up without buying a separate energy drink. It will not help anyone without that bottle, and is not a substitute for a strong cup of coffee if you need a large caffeine dose.
Pros and cons
- Zero calories and no added sugar
- Adds caffeine without a separate energy drink
- Strength adjustable through the Flavor Dial
- Rated for about six 20 oz bottles per cartridge
- Requires a Cirkul bottle and cap to work at all
- Caffeine dose is not fixed, it shifts with the dial setting
- No customer review data included with this listing
Performance notes
Turning the cap's Flavor Dial changes both how strong the caffeine and flavor taste and how many bottles a single cartridge stretches across, so a light setting yields more servings than a strong one from the same cartridge.

How much does one cartridge make?
About six 20 oz bottles worth, though the exact yield depends on how the Flavor Dial is set.
