BioTechUSA Black Blood CAF+ Blueberry

BioTechUSA Black Blood CAF+ is a sugar-free, extreme pre-workout drink powder designed to be mixed with water and taken shortly before and during training. Marketed for hardcore body builders and people doing combat sports, it’s also positioned as a formula to help support leaning out and everyday workout performance. The “CAF+” part signals caffeine being included for a strong stimulant effect, with the brand listing high caffeine content per daily amount.

In terms of purpose, Black Blood CAF+ is built around an energy-focused blend with amino acids, plus added vitamins and minerals that BioTechUSA links to normal energy-yielding metabolism and the reduction of tiredness and fatigue. To finish the formula, it also includes black pepper extract in the form of BioPerine.

Key ingredients highlighted by BioTechUSA include L-arginine hydrochloride, beta-alanine, L-citrulline, malate (malic acid) and L-tyrosine, alongside magnesium, niacin, zinc, vitamin B6, and BioPerine (black pepper fruit extract). The product also provides 400 mg total caffeine across the daily amount, split between caffeine anhydrous and black tea extract.
