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.
High chromatographic purity
HPLC purity >99.9% is normal for research-grade peptides and consistent with the clean chromatogram shown on page 2.
Identity confirmed by mass spectrometry
Mass spectrum matches reference standard for GHK-Cu (CAS 49557-75-7). Chromatogram shows single dominant peak at 0.63 min.
Batch/lot number present
Batch kmbxy76 clearly labeled on COA and visible on vial photos.
Dates are reasonable
Sample received 2026-01-29, tested 2026-02-11, report issued 2026-02-18. All dates are sequential and on or before 2026-07-29.
Dual branding: Finnrick/Krause Analytical
Document header shows 'Finnrick.com' and 'Finnrick Analytics' but footer and signature reference 'Krause Analytical LLC'. This dual branding is unusual but could indicate a white-label or partnership arrangement. Verification URL points to finnrick.com/verify.
Methods described but results not shown
Page 3 describes methods for endotoxins (USP/NF 85) and metals (USP/NF 233), but no actual test results are provided on the COA. Only purity/potency/identity results are shown.
Limited testing scope
COA only reports purity and identity. No microbial, sterility, residual solvent, or water content testing results are provided.
Professional presentation
Document includes chromatogram, mass spectrum comparison, vial photos, detailed methods, and signature. Formatting is consistent with legitimate analytical lab reports.
