- Reduces perceived effort, so hard work feels easier.
- Raises alertness and focus during long efforts.
- Supports energy output.
See caffeine for training and pre-workout for cardio.
Endurance ingredients beyond caffeine
Beta-Alanine supports muscular endurance for repeated hard efforts, complementing caffeine. See Beta-Alanine benefits.
Dose sensibly for long efforts
For long endurance work, a moderate dose usually works best, avoiding overstimulation and a crash. Hydrate well. See pre-workout for cycling.
How PUROX helps endurance
PUROX pairs sensible caffeine with L-Theanine for steady, clean energy, plus Beta-Alanine for endurance, so you go longer without a crash.
