5150 Legendary Series delivers a supercharged hit with over 400mg of caffeine per serving, plus revolutionary energy and nootropic cocoabuterol. Rich Piana originally chose the name "5150" for this ultra-high stimulant pre-workout because he wanted to convey that this pre-workout was not for the normals, but only for the serious stimulant addicts among us. And while Rich wasn't implying that taking a few scoops of 5150 before training would result in a 72-hour “involuntary psychiatric hold”, he wanted to convey that this product was serious! If yes, you may have met the requirements to start training as a true 5% ER; to enter the territory where only a few thrive: massive monster territory. If you're routinely looking for the pain of a long training session and routinely need to be discovered by at least two smaller gym fans, then we'd like to welcome you to the 5150 Legendary Series High Stimulation Pre-Workout. Composed of anhydrous caffeine, dicaffeine malate, theobromine, green tea, yerba mate extract, guarana extract, green coffee bean extract. This is a precise combination of eight types of caffeine and is specifically sourced to create a smooth, extended energy curve, while effectively eliminating the caffeine jitters and "caffeine crash" that accompanies most high-end products. lots of caffeine.
