Black Blood is a BioTechUSA pre-workout product family. The manufacturer sells Black Blood NOX+ and Black Blood CAF+ with different formulas. The name is not a general category of dark-colored, creatine-heavy supplements, and it does not identify a Bucked Up product.
NOX+: distinguish one serving from the daily amount
The official 340 g NOX+ page, checked October 13, 2026, lists 34 servings of 10 g. Its main ingredient table instead reports a 20 g daily amount comprising two servings. The displayed quantities below therefore cover 20 g, not one 10 g serving:
- Caffeine anhydrous: 300 mg
- L-citrulline: 3,000 mg; malic acid: 1,250 mg
- L-arginine hydrochloride: 3,628 mg, providing 3,000 mg L-arginine
- Beta-alanine: 2,400 mg
- Creatine monohydrate: 3,411 mg, providing 3,000 mg creatine
- L-tyrosine: 600 mg
One 10 g serving consequently provides half the table’s amounts, including 150 mg caffeine and 1,500 mg creatine. The 340 g tub contains seventeen 20 g daily amounts. Reporting 34 servings alongside the doubled ingredient figures would overstate what each serving supplies.
The “of which” figures are already contained within their parent compounds. Do not add 3,411 mg creatine monohydrate to its 3,000 mg creatine yield, or add the arginine-hydrochloride weight to its arginine yield. The table also lists L-citrulline and malic acid separately.
CAF+ uses a different serving scheme
BioTechUSA’s 15 g CAF+ sachet listing gives two 7.5 g servings. Each contains 200 mg total caffeine: 179 mg from caffeine anhydrous and 21 mg from black tea extract. The full 15 g daily amount contains 400 mg; the source contributions are included in that total, not additional caffeine.
Per 7.5 g, CAF+ lists 1,050 mg beta-alanine, 1,000 mg L-citrulline and 1,209 mg arginine hydrochloride providing 1,000 mg L-arginine. It has no creatine. Those figures should not be mixed with NOX+ or with older Black Blood marketing pages showing different portion sizes.
Read warnings as well as front-label claims
The pictured NOX+ tub is Tropical Fruit, 340 g. Its front’s 300 mg caffeine and 3,000 mg creatine callouts need the daily-amount context above. A larger number on a front label does not establish a stronger effect per serving.
CAF+ warns against other caffeinated products on the same day and lists several groups for whom it is not recommended, including people with caffeine sensitivity, cardiovascular disease or hypertension. Follow the actual package’s warnings. FDA guidance likewise emphasizes individual caffeine sensitivity; a general daily reference is not a target pre-workout dose.
