Description

Pre-workout built for lifters who love hard training and want aggressive energy, laser focus and sleeve-stretching pumps in one scoop.

5% Nutrition 5150 Stim Crazy Pre-Workout is a high-stimulant formula combines a massive hit of stimulants with clinically respected performance drivers so you can attack heavy sets, sustain high-volume work, and finish strong without the hard crash typical of underdosed products. The Stim-Crazy system delivers over 400 mg of caffeine from eight complementary sources for a smoother, longer curve, and it’s reinforced with Cocoabuterol to elevate mood, thermogenesis and drive. 

The current Legendary Series label features the Stim-Crazy Caffeine Complex at 513 mg and pairs it with targeted nootropics and pump ingredients. In practice, that means fast and sustained energy, improved mind–muscle connection, and nitric-oxide support to move nutrients where they are needed. You get pure L-Citrulline for dense, lasting pumps, Beta-Alanine to buffer fatigue, Taurine for cell hydration and feel, and a focused neuro stack to keep you locked in set after set. 

Mix one scoop with 6–8 oz of water and drink on an empty stomach 15–30 minutes before training. Do not exceed the recommended serving. Because this product is very high in stimulants, assess tolerance with a partial serving if you’re new to strong pre-workouts.
