Supp facts Defy is Black Market Labs' heaviest-dosed pre-workout - 10g of pure citrulline, 5g betaine, and up to 450mg caffeine from six stimulant sources at the full two-scoop serving.
Pre-WorkoutThe brand built Defy with a 40/20 split serving structure specifically so it can flex between a single-scoop "daily driver" dose and a full two-scoop dose that pushes caffeine to 450mg across six different stimulant sources. The pump side is unusually aggressive too - 10g of pure L-citrulline (not citrulline malate) is above what most clinical pump research even tests, paired with a double-strength 5g betaine dose. That range is the point: a customer can run it light most days and reserve the full dose for a PR attempt, which makes it a more flexible recommendation than a single-strength high-stim product. It's still squarely an experienced-user product at full dose, and the label carries an athlete disclosure for anyone competing under drug testing.
