7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
2 of 7 present · 0 passed · 0 failed · 2 reported · 5 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Tested · result on file · core
Compound identity confirmed (e.g. HPLC, mass spec).
HPLC chromatogram shown
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
99.45%
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
Missing lot/batch number
Lot number field shows 'N/A' which is unusual for a legitimate COA. Batch traceability is essential for quality control.
Ambiguous date field
Only 'Analysis date' is provided (2023.08.25). No clear sample date or issue date distinction. Unclear if this is when testing occurred or when report was issued.
High purity with supporting chromatogram
99.45% purity is supported by detailed HPLC chromatogram showing main peak at 12.77 min with area 99.45% and minor impurities quantified.
HPLC method specified
Instrument clearly identified as Acquity H-class Plus Xevo G2-XS QTOF, which is a legitimate high-end analytical instrument.
Limited testing scope
Only purity/identity testing shown. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing documented.
Limited lab information
Lab name 'Weipu' shown with Chinese characters and addresses in Shanghai. Website provided but no accreditation information, QA signature, or analyst identification.
Minimal documentation
Report titled 'Report of Testing' rather than 'Certificate of Analysis'. Very sparse format with minimal quality control documentation, no signatures, no pass/fail criteria.
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (1068 days) — consider whether a retest is warranted for this batch.
