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.

    99.84%

  • Heavy metals

    Tested · passed

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

    As: 0.331 ppm, Cd: 0.121 ppm, Pb: 0.440 ppm, Hg: 0.641 ppm, Cr: 0.759 ppm

  • 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.

    0.13 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

    99.84% purity by HPLC with batch mean 99.74% across 3 samples (std dev 0.1096%), well within normal range for research peptides

  • Identity confirmed

    MOTS-C confirmed by HPLC retention time comparison with reference standard

  • Batch information complete

    Lot CR-MOTSC40-2606-BLUE, COA-2026-NO040O, Accession ACC-2026-5785

  • Dates consistent

    Received 2026-06-20, analyzed and issued 2026-07-02, reasonable turnaround time

  • Lab credentials present

    ILS Laboratories, San Diego CA, ISO/IEC 17025 accredited, signed by Dr. Greg Kalyuzhny

  • Comprehensive testing

    Includes purity, identity, heavy metals, sterility (PCR), endotoxin, and fentanyl screen; all panels passed

  • Missing microbial and residual solvent panels

    No traditional microbial count or residual solvent/water content testing reported; sterility by PCR is present but not a full microbial panel
