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.

1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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, TB-500, BPC-157 identified by HPLC

  • Purity

    Not on this COA · core

    Reported purity percentage for the analyte.

    No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.

  • 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.

  • No purity analysis

    COA reports only assay (quantity) measurements for four peptides but provides no purity percentage or chromatographic purity data. This is a fundamental omission for peptide quality control.

  • Identity confirmation unclear

    HPLC methods listed (TESTMET-CH-310, TESTMET-CH-321) appear to be assay methods. No explicit identity confirmation method (e.g., mass spectrometry, amino acid analysis) is documented.

  • Missing critical safety panels

    No heavy metals, microbial contamination, endotoxin, sterility, or residual solvent/water testing reported. These are standard for research peptides intended for any biological use.

  • No sample/test dates

    COA shows issue date (2026-07-17) but no sample collection date or testing completion date, making it impossible to assess sample age or testing timeline.

  • Lab verification not possible

    Qalitex Inc. claims ISO/IEC 17025:2017 accreditation (AGS-US050824-1) but no verification URL or QR code link provided. Independent verification of accreditation status cannot be performed from this document.

  • Unusual assay reporting

    Results show mass quantities (e.g., '56 mg' vs specification '50 mg') rather than percentage purity or concentration. This is atypical for peptide COAs and suggests quantity verification rather than quality analysis.

  • Batch identification present

    Batch number N260710-001 and lot number SP26-KLV80 clearly documented.
