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.

4 of 7 present · 2 passed · 0 failed · 2 reported · 3 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

    Tested · result on file

    Lead, arsenic, cadmium, mercury, or similar limits.

  • 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

    Tested · result on file · core

    LAL or chromogenic endotoxin assay.

  • 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

    HPLC purity >99.9% with clean chromatogram showing single dominant peak at 6.84 min

  • Mass spectral confirmation

    Mass spectrum shows expected charge states for Tirzepatide (m/z 1613.6, 1216.0, etc.) with ID confirmed

  • Batch/lot number present

    Lot hmby5d2 clearly stated with label claim 50 mg, actual 50.2 mg (100.4% of label)

  • Dates within normal range

    Sample received 2026-04-07, tested 2026-04-15, report issued 2026-04-27 - all dates are sequential and reasonable

  • Established laboratory

    Krause Analytical LLC is a known peptide testing laboratory in Austin, TX with verification URL provided

  • Limited panel results reported

    Methods summary indicates endotoxin and metals testing capability (USP/NF 85, 233) but no numerical results shown on page 1; only purity/identity/potency results displayed

  • Professional presentation

    Multi-page COA with chromatogram, mass spectrum, methods summary, director signature, and watermark consistent with legitimate lab reports

  • Dual branding

    Document shows both 'Finnrick Analytics' and 'Krause Analytical' branding - appears Finnrick may be a reseller/distributor using Krause as the testing lab, which is legitimate but adds complexity
