Stim Crazy Pre-Workout 5150 is formulated to deliver intense energy, laser focus, and peak performance when you need it most. Designed for serious training sessions, this high-stimulant blend helps power through fatigue, enhance endurance, and maximize every rep.

Max daily dose increased from 30 grams to 40 grams of ingredients. Formula updates based on the most recent literature and over 1 million orders & user feedback. Markedly increased energy, focus, drive, and stress resilience. Enhanced vasodilation, explosive power, and muscular endurance. Amplified pump and muscle volume. New S Tier flavor systems. Naturally colored. Less clumpy, less gritty, and improved mix-ability. Gorilla Mode is our turnkey stimulant-based pre-workout formulated for intense pumps, energy, performance and laser focus. With an absurd 40+ grams of potent active ingredients per max dose, this product is fully efficacious from virtually every angle. Included is a maximum efficacious dose of L-Citrulline (10g) alongside topped-out dosages of Hydroprime Glycerol, Betaine, Creatine, and Pink Himalayan Sea Salt. Together, these ingredients will saturate your muscles with blood and intracellular hydration for an intense pump, vascularity, and muscular fullness. This product also contains an efficacious 400 mg of caffeine per max dose as the literature suggests peak ergogenic benefits of caffeine are typically observed at higher dosages. Notably, the potent nootropic complex: (an unheard of 5000 mg L-Tyrosine), 800 mg Alpha-GPC, and 200 mcg Huperzine A, significantly augments the perceived effect from the stim hit, driving a massive dopamine and adrenergic cascade. This synergy will provide a distinct enhancement of focus, mental clarity, sharpness, stress resilience, explosive power, drive, and motivation. Additionally, stacked pre-workouts are notorious for bad taste, horrible mixing, and are generally tough to get down. Not Gorilla Mode. With the help of years' worth of user feedback and over 1 million orders placed of our previous formula, we’ve dialed the flavor systems to be S-Tier (the taste is phenomenal) while improving the mixability and grit substantially.
