NOX+ is the sibling to Black Blood CAF+, and the difference is where the emphasis sits. CAF+ is built around a heavy caffeine dose; NOX+ puts the weight into blood flow and strength work instead, with the stimulant kept to a moderate level.
The NOX complex runs to over 10g per daily amount: 3628mg of L-arginine hydrochloride and 3000mg of L-citrulline for vasodilation, plus 2400mg of beta-alanine. Unusually for a pre-workout it also carries 3000mg of creatine monohydrate, so it covers your strength supplement in the same scoop. Rounding it out are L-tyrosine, malic acid, vitamin C and 150mg of caffeine per serving - present, but a long way short of CAF+.
