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).

    Expected mass: 402.10 g, Measured mass: 402.11 g

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    98.9%

  • 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 purity confirmed

    98.9% purity by HPLC-UV is excellent and typical for research-grade peptide compounds

  • Mass spectrometry confirmation

    Measured mass (402.11 g) matches expected mass (402.10 g) within acceptable tolerance

  • Clear lot number

    Lot number SW-C010-50 clearly stated

  • Appropriate timeline

    Analysis date (2023-08-22) and issue date (2023-08-24) show reasonable 2-day turnaround

  • Lab identification present

    MZ Biolabs with full contact information, analyst name (Ken Pendarvis, ChE), and signature

  • Limited testing scope

    Only identity and purity panels present; no heavy metals, microbial, endotoxin, sterility, or residual solvent testing

  • Professional presentation

    Clear chromatogram, peak list, PubChem reference, and professional layout with watermark

  • External reference provided

    PubChem CID 71587328 provided for independent verification of compound structure

Timing & next steps
