Pre-workout supplements include other components that bodybuilders and professional athletes regularly rely on, consisting of creatine, L-arginine, Betaine, taurine, and β-alanine. Others include guarana, a plant-based stimulant which consists of two times the amount of caffeine per gram compared to coffee beans.2.
