Good to know
This is one of several flavours in the Defib Catalyst range, so if bubble gum isn’t to your taste, the same product is available in other options with the same serving count. Always follow the label for scoop size and how close to training to take it, and keep the tub sealed and away from direct heat between uses to help maintain the powder’s quality.
