BZRK is a high-stim pre-workout from Black Magic Supply - 350mg caffeine, 7g citrulline malate, and BetaO (a trademarked beta-alanine/orotic acid combination) in a reformulated version that dropped an ingredient in the original formula used to contain.
Pre-WorkoutThis is the current, reformulated BZRK - Built around 7g citrulline malate, GlycerPump glycerol, betaine anhydrous, and BetaO, alongside 350mg caffeine and nootropic support from huperzine A and NeuroFactor (a coffee fruit extract). Reviewers describe it as smoother and more focus-oriented than a typical high-stim product despite the caffeine load, though it's still squarely an experienced-user product given the dose. Worth noting for retailers new to the brand: Black Magic Supply also sells a stronger "Overdrive" version, so it's worth confirming with a distributor which specific BZRK formula is being stocked before making claims about caffeine content.
