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.
Dual branding inconsistency
Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding. Header says 'Finnrick.com' and 'Finnrick Analytics Lab # 200907', but footer and signature reference 'Krause Analytical LLC' and director 'Mark C. Krause'. This dual identity is unusual and raises questions about the actual testing entity.
Verification URL domain mismatch
Verification URL is listed as 'https://finnrick.com/verify' but the lab entity is 'Krause Analytical LLC'. The domain does not match the legal entity performing the analysis.
Methods described but results not reported
Page 3 describes detailed methods for Endotoxins (USP/NF 85) and Metals (USP/NF 233), but no actual test results for these panels appear on the COA. This suggests either incomplete testing or incomplete reporting.
High purity with supporting chromatogram
Chromatographic purity of >99.9% is supported by a clean chromatogram showing a dominant peak at 0.47 min with minimal impurities. This is normal for research-grade peptides.
Mass spectrum confirmation
Mass spectrum provided and compared to reference standard (GHK-Cu 52 (0.961)), showing characteristic fragmentation pattern consistent with GHK-Cu identity.
Batch/lot number present
Batch/lot number 's3hzq3t' clearly stated and consistent across document pages.
Date sequence logical
Sample received 2/6/2026, method date 2/17/2026, report issued 2/22/2026 - all dates are sequential and reasonable.
Heavy watermarking
Document has prominent 'FINNRICK' watermarks throughout, which is unusual for a final issued COA and may indicate a draft, sample, or template document.
