PepIndex score
22.5 / 100
1.1/ 5Thinly documentedData coverage
25%
Coverage is the share of scored fields we hold and corroborated for Peptide Crafters. 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 Peptide Crafters legit?
Not on the evidence PepIndex holds. We have no certificate records for Peptide Crafters, so nothing here establishes what is in its vials, and its 22.5/100 rests on business and pricing disclosure alone.
- Peptide Crafters names no testing laboratory that PepIndex could record.
- Its certificates are account required, which limits independent checking.
- On the business side it publishes prices visible without an account.
What this does not tell you
- An absence of certificates in this index is not proof of a problem — it means the evidence a buyer would need has not been published or could not be reached.
- PepIndex has located no independent customer reviews for Peptide Crafters, 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 mass0 lotsView 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.
No certificate records are indexed. Either none are published, or those published could not be read without an account.
Recorded data pointsEvery field with its source, capture date and whether we corroborated it4 verified2 claimed13 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.

Strengths
- Prices are visible without an account
Weaknesses
- No published certificates were located
- Certificates are gated rather than openly readable
- Testing laboratory is not named on the certificates read
- No ISO/IEC 17025 accreditation recorded for the testing lab
- No registered legal entity is disclosed
- No physical postal address is published
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.
