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.

    99.95%

  • Heavy metals

    Tested · passed

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

    As: 0.4794 ppm, Cd: 0.2489 ppm, Pb: 0.0252 ppm, Hg: 0.5017 ppm, Cr: 3.997 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.

    0.077 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

    99.95% purity by HPLC with conformity testing across 3 samples (mean 99.78%, std dev 0.24%). This is normal for research peptides.

  • Identity confirmed

    HPLC retention time match confirmed Double Agonist identity. Chromatogram shows single dominant peak.

  • Batch information complete

    Lot number CR-2XAG40-2607-Green, COA number COA-2026-IKRR2C, Accession ACC-2026-7829 all clearly stated.

  • Dates consistent

    Received 2026-07-03, analyzed and issued 2026-07-10. All dates are reasonable and sequential.

  • Lab credentials stated

    ILS Laboratories, San Diego address, phone, ISO/IEC 17025 accreditation claimed. Verification URL and access code provided.

  • Comprehensive testing

    Full QC panel includes purity, identity, heavy metals, endotoxin, sterility, and fentanyl screen. Missing only microbial count and residual solvents.

  • Fentanyl screening included

    Immunoassay fentanyl screen (50 ng/mL cutoff) shows Not Detected, which is appropriate for research peptides.

  • Cannot independently verify lab

    ILS Laboratories is not widely known in public databases. The verification URL and credentials cannot be confirmed without live access. This is not evidence of fabrication, but limits independent verification.
