5150 High Stimulant Pre-Workout delivers a supercharged punch with over 400mg of Caffeine per serving, plus the revolutionary energy and nootropic Cocoabuterol for more than 500mg of total stimulant per serving! With just a single scoop of 5150® you'll surge with over 400mg of caffeine through your veins. Our precise 'STIM-JUNKIE' complex combines 8 types of caffeine for a smooth, extended energy curve while nearly eliminating the caffeine jitters or crash that accompany most pre-workouts. What is the meaning of 5150? Rich Piana originally went with the name “5150” for this ultra-high stimulant pre-workout because he wanted to convey that this pre-workout was not for the ordinary, but for only the serious stim junkies among us. And while Rich wasn’t insinuating that taking a few scoops of 5150® Pre-workout would result in a 72-hour “involuntary psychiatric hold”, he wanted to convey that this product meant business!
