What is BZRK pre-workout?
BZRK is a named pre-workout from Black Magic Supply. The manufacturer’s current product page presents a 25-serving powder. Treating “BZRK” as shorthand for any extreme-stimulant blend obscures which ingredients a buyer is actually considering.
This guide covers the standard BZRK powder and the shared online label reviewed on October 12, 2026. It does not establish the formula of Voodoo, Overdrive, or older BZRK versions. Match the full product name and the panel on your own tub before comparing doses.
What the shared label discloses
The official Supplement Facts image lists approximately one 20.17 g scoop and 25 servings. Its main amounts are:
- L-citrulline DL-malate 2:1: 7,000 mg
- Beta-O, containing beta-alanine and orotic acid: 3,200 mg
- GlycerPump, a 65% glycerol powder: 2,500 mg
- Possessed Matrix: 1,620 mg
- Betaine anhydrous: 1,000 mg
- CognatiQ coffee-fruit extract: 75 mg
- AstraGin: 50 mg
The citrulline-malate amount includes the malate portion. Likewise, Beta-O’s combined weight does not establish a separate beta-alanine dose. The Cosmic Burst photograph identifies the pictured flavor, but the shared panel’s serving weight should not be assumed to fit every flavor.
How much caffeine does BZRK contain?
The reviewed official panel does not disclose total caffeine. Its Possessed Matrix contains caffeine anhydrous and ZumXR extended-release caffeine alongside L-tyrosine, Adhatoda vasaka extract, a labeled kola-nut ingredient and a huperzine-A preparation. The 1,620 mg matrix weight cannot be used as a caffeine figure.
There is another unresolved detail: the ingredient called kola nut is paired with the botanical name Areca catechu. Ask Black Magic to clarify that identity and provide total caffeine from every source for the exact flavor and lot. A retailer’s number or an older label cannot settle those questions.
What to check before choosing it
The manufacturer describes mixing a scoop with water before training and mentions a smaller tolerance assessment. Those directions do not resolve the missing stimulant quantities. Feeling comfortable after a small amount does not establish the safety of the complete formula.
The FDA advises caution when caffeine amounts are undeclared and notes that sensitivity, medications and health conditions affect individual responses. Avoid adding other caffeinated supplements while the dose remains uncertain.
Bottom line
BZRK has several disclosed ingredient amounts, but important label questions remain. Resolve them before using the product or treating it as equivalent to another pre-workout.
