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 HPLC purity confirmed

    Chromatographic purity >99.9% by HPLC-UV/MS with clean chromatogram showing single dominant peak at 6.43 min retention time

  • Mass spectrum identity confirmed

    Mass spectrum shows expected m/z peaks (1195, 1586) matching reference standard for Retatrutide (CAS 2381089-83-2)

  • Batch/lot number present

    Batch/Lot 4r6cshf clearly stated with Lab # 200329

  • Dates are consistent and valid

    Sample received 2026-01-23, method date 2026-02-03, report issued 2026-02-11 - all dates are sequential and on or before 2026-07-29

  • Dual branding creates confusion

    Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding. Header says 'Finnrick.com' and 'Finnrick Analytics' but footer and signature reference 'Krause Analytical LLC'. This dual identity is unusual and may indicate a reseller/broker relationship or rebranding, but is not explained on the COA.

  • Verification URL domain mismatch

    Verification URL is https://finnrick.com/verify but the testing lab is stated as Krause Analytical LLC. The relationship between Finnrick and Krause is unclear from the document.

  • Methods described but results not shown

    Page 3 describes methods for Endotoxins (USP/NF 85) and Metals (USP/NF 233) testing, but no actual test results for these panels appear on the COA. This suggests testing may not have been performed or results were omitted.

  • Limited testing scope

    Only identity and purity testing results are provided. No heavy metals, endotoxin, microbial, sterility, or residual solvent/water content results are shown despite methods being described.

  • Professional presentation with supporting data

    COA includes chromatogram, mass spectrum comparison to reference standard, detailed methods summary, and proper laboratory identification with address and director signature
