Stealth Research Labs
Publishes 14 lot-level certificates, every one signed by Bioviridian and independently retrievable from that laboratory’s own public lookup — each vendor-hosted copy byte-identical to the laboratory’s. Assayed mass runs a mean 3.3% above label across the ten single-compound lots read here, and purity is 99.6–99.9% throughout. Prices are ungated. Dallas, Texas; trades as Stealth Research Labs LLC. Payment is by irreversible methods only, and no postal address or laboratory accreditation is on record.

PepIndex score
80.1 / 100
4.0/ 5Well documentedData coverage
91%
Coverage is the share of scored fields we hold and corroborated for Stealth Research Labs. A score built on a handful of unchecked claims and a score built on forty verified data points are not the same finding, so both numbers are always published together. How coverage is computed.
Is Stealth Research Labs legit?
Yes, on the evidence PepIndex holds. We have read 10 certificate records for Stealth Research Labs, all issued by Bioviridian Inc., and score it 80.1/100 on 91% data coverage — rank 12 of 58.
- Across those lots the mean assayed purity is 99.79%, and the weakest single lot came back at 99.65%.
- Every lot with both figures assayed at or above its label claim, so none was underfilled.
- PepIndex holds no ISO/IEC 17025 accreditation record for the laboratory on those certificates, Bioviridian Inc., either way.
- Its certificates can be read without an account, so anyone can check these figures.
- On the business side it publishes a named legal entity and prices visible without an account.
What this does not tell you
- PepIndex has located no independent customer reviews for Stealth Research Labs, so nothing here speaks to its service or fulfilment.
- A score measures what a vendor publishes about its testing and its business. It does not measure the contents of any vial a buyer actually receives, and PepIndex does not commission its own assays.

Discrepancy is computed as the absolute difference between labeled and assayed mass, divided by the labeled mass. A vendor-published certificate is a claim; only an independently commissioned assay is treated as corroboration.

A tag of verified means we opened the cited source and confirmed the value; published means we recorded the vendor’s own published information, taken at face value. Both count in full; only a value with no checkable source earns nothing. Fields older than 30 days are marked stale.

Score history
Daily score history is recorded from the first nightly snapshot onward. Nothing is backfilled, so the record starts the day recording started.
Strengths
- Publishes 14 certificates on its own site; 10 read and recorded here
- Certificates are readable publicly, without an account
- Testing laboratory named on certificates (Bioviridian Inc.)
- Operates under a named legal entity (Stealth Research Labs LLC)
- Prices are visible without an account
Weaknesses
- No ISO/IEC 17025 accreditation recorded for the testing lab
- No physical postal address is published
- No independent third-party reviews located
Regulatory & enforcement record
No adverse regulatory or enforcement action on record. We record authority actions — FDA warning letters, import alerts, seizures, criminal charges — when located. Self-reported reviews are deliberately not scored, because for this market they can be manufactured.
How this score was calculatedEvery signal, its weight and the arithmetic — reconstructable by handrubric v1.11.0View calculation →Hide ↑
Each criterion is scored out of 100 over the signals we could assess, then weighted into the overall figure. Within a criterion, a signal contributes weight × merit × credit: merit is how good the recorded value is, credit is what its provenance earns — 1.00 for a value with a checkable source, 0 for a value recorded without one. A missing signal counts as a partial gap — half its weight — so a vendor that publishes what others leave blank scores higher, while a blank still costs; a value recorded without a source counts in full and earns nothing, so omitting one can never raise a score. A criterion with no data at all — track record when no independent reviews are locatable — is set aside and the remaining weights renormalised; the coverage figure, shown alongside, reports how complete the assessment is.
