PepIndex score
71 / 100
3.6/ 5Well documentedData coverage
95%
Coverage is the share of scored fields we hold and corroborated for Northline 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 Northline Labs legit?
Yes, on the evidence PepIndex holds. We have read 33 certificate records for Northline Labs, issued by 2 laboratories, and score it 71/100 on 95% data coverage — rank 20 of 57.
- Across those lots the mean assayed purity is 99.46%, and the weakest single lot came back at 98.31%.
- 12 of 33 lots assayed below the mass printed on the label.
- PepIndex records those laboratories as holding ISO/IEC 17025 accreditation.
- Its certificates can be read without an account, so anyone can check these figures.
- On the business side it publishes a postal address and prices visible without an account.
What this does not tell you
- PepIndex has located no independent customer reviews for Northline 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.
Certificate recordsLot-level results with labeled versus assayed mass33 lots3.1% mean deviationView all →Hide ↑
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.
Recorded data pointsEvery field with its source, capture date and whether we corroborated it9 verified9 claimed1 not recordedView all →Hide ↑
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.
Testing
- Testing laboratory
- ILS LaboratoriesVerified5 Oct 2026sourceEleven of the twelve certificates read on 2026-10-05 are signed by ILS Laboratories (the twelfth by Horizon Analytical), as were 24 of the 27 read on 2026-07-31. The crawl had recorded 'Pending publication', which is the COA page's placeholder for a lot whose certificate is not yet posted, not a laboratory.
- ISO/IEC 17025 accreditation
- YesVerified5 Oct 2026sourceRe-checked 2026-10-05: ils-lab.com states it is 'ISO/IEC 17025 accredited for activities within its accredited scope' and its about page says 'ISO/IEC 17025 Accredited Lab in San Diego'. No accreditation body or certificate number is published, so the claim is the laboratory's own.

What the certificates test
Beyond purity and mass. Each row is an assay the laboratory ran and the verdict its own certificate printed. Coverage is recorded, not figures: these documents are tables, and the specification and the result are not reliably separable once the text is extracted.

Third-party reviews
Shown for reference and kept out of the score. Review platforms can be gamed — ratings bought, competitors brigaded, profiles removed — so nothing here is treated as evidence of what is in a vial. The score is computed from certificates and documentation alone.

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.
