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).

    45.2% Acetonitrile

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.1%

  • 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

    99.1% purity by R-HPLC is within normal range for research peptides and matches specification ≥99%

  • Identity confirmed by R-HPLC

    Retention time matches analytical standard (45.1% vs 45.2% acetonitrile)

  • Batch number present

    PPA-WL-PT141-P000706

  • Dates are consistent

    Sample received 2026-07-13, analyzed and issued 2026-07-27 (14-day turnaround)

  • Lab verification not possible

    No URL or contact information provided to independently verify Pacific Coast Biologics Inc

  • Limited testing scope

    Only appearance, purity, identity, and quantification tested. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing

  • Professional presentation

    Document includes chromatogram, molecular formula, proper disclaimer, and signature
