Performance Bullet delivers fast-acting caffeine chews designed to boost energy, focus and endurance when you need it most.
Performance Bullet was founded by ultra runner and marathon champion David Hellard, built from a simple idea during a race where convenience and performance mattered most. What started as a solution to a dropped caffeine tablet has evolved into a brand focused on delivering fast, effective energy in the most practical way possible.
At the core of Performance Bullet is its unique buccal absorption method. By chewing instead of swallowing, caffeine is absorbed directly through the cheeks into the bloodstream, working up to three times faster than traditional gels, drinks or pills. This allows athletes to respond instantly to fatigue, push harder and maintain focus during key moments.
Each chew combines a concentrated caffeine dose with a blend of electrolytes, supporting both energy levels and hydration. With low calories and clean ingredients, Performance Bullet offers a more efficient alternative to sugary drinks and bulky fuelling options, making it ideal for races, training sessions or even everyday energy needs.
Driven by a science-led approach, the brand is committed to delivering optimally dosed, no-nonsense products that perform when it counts. Whether you are chasing a personal best, staying sharp in competition or simply needing a reliable energy lift, Performance Bullet is built to help you move faster and think clearer.
Performance Bullet delivers fast-acting caffeine chews designed to boost energy, focus and endurance when you need it most.
Because the chew is absorbed through the cheeks, caffeine enters the bloodstream directly, working up to three times faster than traditional methods.
Caffeine helps mobilise fat for energy, reduces perceived effort and fatigue, and improves focus and concentration during exercise.
They can be used before or during exercise, especially when fatigue starts to set in, but should always be tested in training first.
Each chew contains around 85 to 100mg of caffeine depending on the flavour, providing a concentrated and effective dose.
