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).

    Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.57%

  • Heavy metals

    Tested · passed

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

    All Not Detected

  • 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 with conformity testing

    99.57% purity confirmed across 3 samples (mean 99.20%, std dev 0.46%), with HPLC chromatogram and detailed methodology. This is normal for research peptides.

  • Identity confirmed by HPLC-RTM

    MOTS-C confirmed by retention time match with reference standard. Fentanyl screen also passed (not detected).

  • Clear batch identification

    Lot CRMTS-40-2605-1, COA #COA-2026-E85OFQ, Accession #ACC-2026-3349. Net peptide content 41.8 mg (labeled 40 mg).

  • Dates are consistent and current

    Received 05/27/2026, analyzed 06/01/2026, issued 06/01/2026. All dates are on or before 2026-07-28 and logically sequenced.

  • ISO/IEC 17025 accredited lab

    ILS Laboratories, San Diego, CA. Claims ISO/IEC 17025 accreditation. Verification URL and access code provided (MN4SR7XQ).

  • Comprehensive testing panel

    Full QC panel includes purity/identity (HPLC), heavy metals (ICP-MS), endotoxin (USP <85>), and sterility (PCR). Missing only microbial count and residual solvents/water content.

  • Microbial count panel absent

    No microbial enumeration (total aerobic count, yeast/mold) reported. Sterility testing (PCR) is present but does not replace quantitative microbial limits testing.

  • Professional presentation

    Well-formatted 2-page COA with clear tables, chromatogram, QR code for verification, lab director signature, and detailed methodology notes.
