VROOM VROOM, BABY! Caffeine is THE most widely consumed psychoactive substance in the world, and it's one of the most commonly available ergogenic aids (i.e. substances that can improve athletic performance). In this episode we talk about the research behind caffeine and its effect on endurance performance, "fast" and "slow" metabolizers, dosing, timing, the placebo effect, caffeine's effect on heart rate, and more!
