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.

    >99.95%

  • 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 >99.95% purity with clean chromatogram showing single dominant peak at 6.52 minutes

  • Identity confirmed by mass spectrometry

    Mass spectrum matches reference spectrum for Retatrutide with characteristic m/z peaks at 1185, 1579

  • Batch/lot number present

    Lab # 129620, Test Certificate ID: 5yyx57h

  • Dates are consistent and reasonable

    Sample received 10/14/2025, testing performed 10/22/2025, report issued 10/23/2025 - all dates are sequential and within normal turnaround time

  • Testing lab identified with contact information

    Krause Analytical LLC, 8127 Mesa Drive Suite B-206, Austin, TX 78759. Signed by Mark C. Krause, Laboratory Director

  • Dual branding requires verification

    Document shows both Finnrick Analytics/Finnrick.com branding and Krause Analytical LLC. Footer indicates 'Finnrick Testing Certificate © 2026 Finnrick Analytics LLC and its suppliers' suggesting Finnrick may be a reseller/distributor using Krause as contract lab

  • Limited testing scope

    Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic research-grade peptide testing but limits comprehensive quality assessment

  • Professional presentation with supporting data

    Includes sample photos, full chromatogram, and comparative mass spectra. Watermarked throughout. Professional layout consistent with analytical lab reports
