Supp facts Black Market Labs Rule is the brand's most concentrated focus-driven pre-workout - 485mg caffeine plus eight nootropic ingredients including uridine and lion's mane, a rarer combination in this category.
Pre-WorkoutRule goes further into nootropics than any other product in the Black Market lineup, including the brand's own Adrenolyn Nootropic: alongside a heavy 485mg caffeine load from multiple sources, it adds uridine monophosphate (uncommon in pre-workouts), 800mg lion's mane, alpha GPC, dendrobium, and eria jarensis, all aimed at sustained mental lock-in rather than just alertness. Pump support (citrulline, beta-alanine, pink Himalayan salt) is present but secondary to the focus side of the formula. Given the caffeine load and the ingredient list overlap with the brand's Underground and Defy formulas, this is squarely an experienced-stimulant-user product, and it's worth steering customers away from stacking it with any other Black Market stim pre-workout.
