Not checked yet
- 3 of 3 flavors on the brand's store (2026-10-30) have no panel read yet.
- Retail labels have not been compared with the brand's own store.
- Earlier labels may exist that the Record has not recovered; a missing observation is not proof nothing changed.
Labels read from the brand's own store (DTC) channel only. Other channels may sell a different label. The panel is declared product-wide; no flavor-specific panel has been read. US market only.

Method
How this page was made.
What FormulaSignal did
- Read the label Black Market Labs published, dated Oct 30, 2026, twice and independently: 75 of 75 fields agreed.
- Kept that label with the day each was seen and its source.
- Counted a change only between two dated labels of the same flavor, size and sales channel: 0 confirmed changes on file.
- Printed every gap the Record knows about, above, instead of leaving it out.
What it did not do
- No look inside your tub. A product record does not establish what a particular container holds, and label dates are not manufacture dates.
- No taste test and no lab test. Every figure is what a label or a brand's own page declares, not what was measured in a tub.
- No score and no winner. Differences are measured and shown; nothing is rated.
- No payment and no preview. No brand paid to appear, and none saw this page before it was published.
- No health advice. Whether an ingredient or an amount suits you is a question for a clinician.

My Black Market Labs Underground High Stimulant Pre-workout tastes or feels different. Is it a new formula or a bad batch?
A label can answer half of that: whether the formula on the label changed. Compare the Supplement Facts panel on your tub with the label dated Oct 30, 2026 on this page (it declares High Stimulant & Focus 3220 mg, L-Taurine 1000 mg and Dendrobium nobile 10:1 (stem) Extract 600 mg per serving). If your amounts differ, you hold a different label from the one on file. If they match, the label does not explain the difference. FormulaSignal does not test what is inside a tub.
