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 confirmed

    HPLC-UV/MS shows >99.9% purity with clean chromatogram showing single major peak at 0.63 min retention time

  • Identity confirmed by mass spectrometry

    Mass spectrum matches reference standard for GHK-Cu (CAS 49557-75-7); molecular ion peaks visible in MS data

  • Batch/lot number present

    Batch 9mkr2fk clearly marked on COA and visible on vial photographs

  • Dates are reasonable and consistent

    Sample received 1/29/2026, testing performed 2/11/2026, report issued 2/18/2026 - all dates are sequential and within normal timeframes

  • Dual branding creates confusion

    Document shows both 'Finnrick' branding (header, verification URL) and 'Krause Analytical LLC' (performing lab, signature, methods). While contract testing arrangements exist, the relationship between Finnrick.com and Krause Analytical is not explicitly stated on the COA

  • Lab verification unclear

    Krause Analytical LLC appears to be a legitimate analytical lab, but the Finnrick.com domain and verification URL cannot be independently verified from the document alone

  • Limited testing panels

    Only identity and purity panels performed. Methods summary describes endotoxin and heavy metals testing procedures, but no results are provided for these tests on this specific sample

  • Professional presentation with supporting data

    COA includes chromatogram, mass spectrum comparison, detailed methods summary, and photographs of tested vial - all consistent with legitimate analytical lab reporting
