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.

    99.76%

  • 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.

  • Branding inconsistency

    Document shows dual branding: 'Finnrick Analytics' and 'Krause Analytical LLC' with overlapping identities. Header says 'Finnrick.com' and 'Finnrick Analytics Lab #200632', but footer and signature reference 'Krause Analytical LLC' and 'Mark C. Krause, Laboratory Director'. This suggests either a reseller/white-label arrangement or potential document manipulation.

  • Lab verification unclear

    While a verification URL is provided (https://finnrick.com/verify), the actual testing lab appears to be Krause Analytical LLC at 8127 Mesa Drive Suite B-206, Austin, TX 78759. The relationship between Finnrick and Krause Analytical is not explained on the COA.

  • High purity with supporting data

    99.76% chromatographic purity is supported by clean HPLC chromatogram showing dominant peak at 6.59 min with minimal impurities. This is normal for research-grade peptides.

  • Mass spectrum confirmation

    Mass spectrum shows m/z 1586 matching reference standard for Retatrutide, with ID confirmed by HPLC-UV-MS. CAS number 2381089-83-2 provided.

  • Methods described but results missing

    Page 3 describes methods for Endotoxins (USP/NF 85) and Metals (USP/NF 233), but no actual test results are shown in the COA. Only purity/potency/identity results are reported.

  • Dates are reasonable

    Sample received 1/29/2026, method date 2/8/2026, report issued 2/18/2026. All dates are sequential and within normal turnaround time, and all are on or before today (2026-07-29).

  • Batch documentation present

    Batch/Lot c4quny3 clearly marked with photos of labeled vial. Lab number 200632 and Project 145031 provided for traceability.

  • Watermark overlay

    Large 'FINNRICK' watermark overlays the entire document, which is unusual for official COAs and may indicate a sample/draft version or reseller branding.
