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.

5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).

    GHK-Cu + KPV Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.19%

  • Heavy metals

    Tested · passed

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

    All Not Detected (As, Cd, Cr, Hg, Pb)

  • 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 · passed · core

    LAL or chromogenic endotoxin assay.

    NMT 0.05 EU/mL

  • Sterility

    Tested · passed

    Sterility testing where applicable.

    No Growth

  • 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

    99.19% purity by HPLC with conformity testing across 3 samples (mean 99.19%, std dev 0.0047%), all passing specification of ≥95.0%

  • Identity confirmed

    Both GHK-Cu and KPV confirmed present by HPLC retention time matching with reference standards

  • Comprehensive testing panel

    Includes purity, identity, heavy metals (5 elements), endotoxin, sterility, and fentanyl screening. Microbial and residual solvent panels not performed.

  • Batch information complete

    Lot number CR2604GHKKP60-01, COA number COA-2026-P0FPZZ, accession ACC-2026-3008, with QR code and access code T3GJ9H2E for verification

  • Date sequence logical

    Received 2026-05-22, analyzed 2026-06-05, issued 2026-06-05 (13-day turnaround, reasonable for full panel)

  • Lab credentials present

    ILS Laboratories claims ISO/IEC 17025 accreditation, provides physical address (8222 Vickers St, Suite 106, San Diego, CA 92111), phone (619) 329-3999, website ils-lab.com, and verification portal

  • Professional presentation

    Well-formatted 2-page COA with chromatogram, conformity testing table, detailed methodology notes, lab director signature, and proper disclaimers

  • Additional screening included

    Fentanyl immunoassay screening included (not detected), which is unusual but increasingly common for research peptides given contamination concerns in supply chain
