Alpha Neon DARKSIDE® ONSLAUGHT™ is the apex of pre-workout engineering—a brutal, high-powered fusion of all Alpha Neon pre-workout systems combined into one monstrous formula. Built exclusively for experienced users, ONSLAUGHT™ pushes intensity, focus, pumps and aggression to extremes. This is not a beginner’s product—it is a full-throttle descent into peak performance, laser focus and skin-tearing pumps. Welcome to your darkest side yet… welcome to DARKSIDE® ONSLAUGHT™.
ONSLAUGHT™ delivers a meticulously engineered combination of nitric oxide boosters, adaptogens, stimulants and nootropics to elevate every aspect of performance. L-citrulline and stabilised glycerol saturate the muscles for vicious pumps, while N-acetyl-tyrosine, CDP-choline, Lion’s Mane and Bacopa create razor-sharp cognitive focus. Bitter orange, guarana and caffeine deliver explosive but controlled intensity, and powerful botanical extracts like white willow bark, PARADOXINE® and Cocobuterol® enhance thermogenesis, drive and endurance. DARKSIDE® ONSLAUGHT™ is formulated for lifters who want the most aggressive and complete pre-workout experience possible.
