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 + BPC-157 + TB-500 + KPV Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.52%

  • Heavy metals

    Tested · passed

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

    As: 0.7163 ppm, Cd: ND, Pb: ND, Hg: 0.8077 ppm, Cr: ND

  • 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.

    0.077 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 with conformity testing

    99.52% purity with three conformity samples tested (mean 99.51%, std dev 0.0125%), demonstrating consistency and quality control rigor

  • Multi-component blend identity confirmed

    All four peptide components (GHK-Cu, BPC-157, TB-500, KPV) confirmed present by HPLC retention time matching

  • Comprehensive testing panel

    Includes purity, identity, heavy metals, sterility (PCR), endotoxin, and fentanyl screening. Missing only microbial count and residual solvent panels

  • Clear batch identification

    Lot number CR-KLOW-80MG-2607-Black, COA number COA-2026-XLDPAB, Accession ACC-2026-7832

  • Appropriate timeline

    Sample received 2026-07-03, analyzed and issued 2026-07-10 (7-day turnaround)

  • ISO/IEC 17025 accredited laboratory

    ILS Laboratories claims ISO/IEC 17025 accreditation with physical address in San Diego, CA and verification portal

  • Professional presentation with QR verification

    Includes HPLC chromatogram, QR code for verification, access code 6JZH598X, and detailed methodology notes

  • Fentanyl screening included

    Immunoassay fentanyl screen (50 ng/mL cutoff) shows 'Not Detected' - unusual but increasingly common for research peptide vendors addressing contamination concerns
