PepIndex score
88.9 / 100
4.4/ 5Extensively documentedData coverage
94%
Coverage is the share of scored fields we hold and corroborated for Ascend Science. 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 Ascend Science legit?
Yes, on the evidence PepIndex holds. We have read 29 certificate records for Ascend Science, issued by 3 laboratories, and score it 88.9/100 on 94% data coverage — rank 4 of 57.
- Across those lots the mean assayed purity is 99.73%, and the weakest single lot came back at 99.46%.
- 1 of 29 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 Ascend Science, 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 mass29 lots7.1% 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.

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.

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.
