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 · 2 passed · 0 failed · 0 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 · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.9%
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.
Identity confirmed by mass spectrometry
Mass spectrum matches reference standard for Tirzepatide (CAS 2023788-19-2)
Batch/lot number present
Lot j9f35yh clearly marked on certificate and vial images
Dates are consistent and reasonable
Sample received 2/6/2026, tested 2/14/2026, report issued 2/20/2026 - all dates are logical and sequential
Branding inconsistency
Document shows dual branding: 'Finnrick' (header, URL) and 'Krause Analytical LLC' (footer, signature, methods). This may indicate a vendor/lab relationship but creates confusion about the actual testing entity.
Verification URL domain mismatch
Verification URL points to finnrick.com/verify but lab name is Krause Analytical LLC. Cannot verify if this URL is functional or legitimate without external check.
Limited testing panels
Only identity and purity panels performed. Methods summary describes endotoxin and metals testing procedures but no results are provided for these tests.
Professional presentation
Document includes detailed chromatogram, mass spectrum comparison, methods summary, and proper USP/NF references
High purity confirmed
Chromatographic purity >99.9% with clean chromatogram showing single dominant peak at 6.70 min
