PepIndex score

76.4 / 100

3.8/ 5Well documented

Data coverage

92%

Coverage is the share of scored fields we hold and corroborated for Koi Peptides. 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 Koi Peptides legit?

Third-party testedComputed from this profile’s stored record, not written by hand

Yes, on the evidence PepIndex holds. We have read 8 certificate records for Koi Peptides, issued by 3 laboratories, and score it 76.4/100 on 92% data coverage — rank 15 of 57.

  • Across those lots the mean assayed purity is 99.51%, and the weakest single lot came back at 98.96%.
  • 3 of 8 lots assayed below the mass printed on the label.
  • PepIndex holds no ISO/IEC 17025 accreditation record for those laboratories either way.
  • The laboratory named on Koi Peptides's own profile does not match the laboratory on the certificates PepIndex has read, so the stated name is not relied on here.
  • Its certificates are age gated, which limits independent checking.
  • On the business side it publishes a named legal entity, a postal address and prices visible without an account.

What this does not tell you

  • PepIndex has located no independent customer reviews for Koi Peptides, so nothing here speaks to its service or fulfilment.
  • Because its certificates are not openly readable, a buyer cannot verify a specific lot without the vendor's cooperation.
  • 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.

  • No independent third-party reviews located

What the certificates test

read from 1 certificate

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

Not part of the score

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 →

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.
