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% is excellent and typical for research-grade peptides

  • Mass spectral confirmation

    Identity confirmed by HPLC-UV-MS with mass spectrum showing expected m/z peaks (641.0, 321.3 consistent with SS-31)

  • Batch/lot number present

    Batch c957k8k clearly documented

  • Dates within normal range

    Sample received 2026-05-04, tested 2026-05-08, report issued 2026-05-13 - all dates are logical and sequential

  • Established laboratory

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

  • Methods described but results not shown

    Page 4 describes methods for endotoxin and heavy metals testing (USP/NF 86, USP/NF 233) but numerical results are not displayed on the COA pages provided

  • Professional presentation

    Document includes chromatogram (page 2), mass spectrum (page 3), methods summary (page 4), signature, and watermark throughout

  • Potency within specification

    54.7 mg recovered vs 50 mg label claim = 109.4% of label, within typical acceptable range for lyophilized peptides
