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.

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.

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 purity confirmed
Chromatographic purity >99.9% by HPLC-UV/MS with supporting chromatogram showing single dominant peak at 0.47 min
Identity confirmed
Mass spectrum matches reference standard for GHK-Cu (CAS 49557-75-7); mass spectrum data provided on page 2
Batch/lot documented
Batch/Lot 8xvxg79 clearly stated; Lab # 200910; Project 145052
Dates within normal range
Sample received 2/6/2026, method date 2/17/2026, report issued 2/22/2026 - all dates are sequential and reasonable
Dual branding inconsistency
Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding throughout. Header says 'Finnrick.com' and 'Finnrick Analytics Lab # 200910', but footer and signature reference 'Krause Analytical LLC' and director Mark C. Krause. This dual branding is unusual and may indicate a reseller/white-label arrangement, but is not explained on the COA.
Verification URL domain mismatch
Verification URL is https://finnrick.com/verify but the actual testing lab appears to be Krause Analytical LLC. The relationship between Finnrick and Krause Analytical is not clarified on the document.
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 for these panels appear on the COA. Only purity/potency/identity results are provided.
Professional presentation
Document includes chromatogram, mass spectrum comparison, detailed methods summary, and proper USP/NF method references
