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.

  • Dates are reasonable and consistent

    Sample received 2026-06-09, tested 2026-06-11, report issued 2026-06-16. All dates are sequential and on or before 2026-07-29 (today).

  • High chromatographic purity

    HPLC purity >99.9% is excellent and typical for research-grade peptides. Chromatogram shows single dominant peak consistent with high purity.

  • Identity confirmed by mass spectrometry

    Mass spectral match confirmed via HPLC-UV-MS. Mass spectrum on page 3 shows expected m/z peaks for Tirzepatide including 1613.1 (base peak) consistent with multiply-charged peptide ions.

  • Batch/lot number present

    Batch x5qmv2y clearly labeled on vial images and throughout document.

  • Testing lab identified

    Krause Analytical LLC, 8127 Mesa Drive Suite B-206, Austin, TX 78759. Lab director Mark C. Krause signature present. Verification URL provided: https://finnrick.com/verify

  • Limited testing panels

    Only identity and purity panels performed. Methods for endotoxin and heavy metals are described on page 4 but no results are shown. Microbial, sterility, and residual solvent testing not performed. This is not uncommon for basic peptide analysis but limits comprehensive quality assessment.

  • Professional presentation

    Document includes detailed chromatogram (page 2), mass spectrum (page 3), and methods summary (page 4). Formatting is consistent with professional analytical lab reports. Watermark present throughout.

  • Dual branding requires clarification

    Document shows both 'Finnrick Analytics' and 'Krause Analytical LLC' branding. Header says 'Finnrick Testing Certificate' but footer and signature reference Krause Analytical. This may indicate a vendor/lab relationship but creates minor ambiguity about the actual testing entity.
