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).

    Confirmed (BPC-157 + TB-500)

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.50%

  • 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

    99.50% peptide purity by HPLC area normalization, exceeds ≥95.0% specification. This is normal for research-grade peptides.

  • Dual peptide identity confirmed

    Both BPC-157 and TB-500 confirmed present by HPLC retention time matching against reference standards.

  • Quantitative blend analysis

    Net blend peptide content 10.4mg (BPC-157: 6.53mg, TB-500: 3.82mg) matches labeled 10mg content within acceptable variance.

  • Fentanyl screening performed

    Immunoassay screening for fentanyl (50 ng/mL cutoff) returned Not Detected, passing safety check.

  • Complete batch traceability

    Lot Number 00233, Accession ACC-2026-7277, COA COA-2026-K5ZZYM all clearly documented.

  • Appropriate timeline

    Sample received 2026-07-01, analyzed and issued 2026-07-10. 9-day turnaround is reasonable for HPLC testing.

  • ISO/IEC 17025 accreditation claimed

    ILS Laboratories claims ISO/IEC 17025 accreditation. Lab director signature (Dr. Greg Kalyuzhny) present. Contact information and verification URL provided.

  • HPLC chromatogram included

    UV chromatogram at 214nm shows two distinct peaks consistent with a two-peptide blend, supporting the reported identity and purity.

  • Limited testing scope

    COA only includes identity, purity, and fentanyl screening. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing. This is common for basic peptide COAs but limits comprehensive quality assurance.

  • Professional presentation

    Document formatting is clean, consistent, and professional. QR code for verification, clear data tables, methodology notes, and accreditation footer all present.
