According to user communities, the GoSip, Inflow, Fission, Frosted Iced Coffee, and Gateway Tea lines contain caffeine, while the majority of Cirkul's other flavor cartridges are caffeine-free. Whether you're seeking a pre-workout boost, a morning pick-me-up, or are sensitive to stimulants, it's crucial to know which Cirkuls have caffeine before purchasing.

According to product listings and customer forums, a single Cirkul Go Sip flavor cartridge contains a total of 390 mg of caffeine. This means the final concentration, and how much caffeine is in a Cirkul Go Sip, depends entirely on the adjustable flavor dial and how long the cartridge lasts.
