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).

    NAD+ Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.00%

  • Heavy metals

    Tested · passed

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

    All Not Detected (As, Cd, Cr, Hg, Pb)

  • 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.

    99.00% purity by HPLC with conformity testing across 3 samples (mean 99.00%, std dev 0.1551%) demonstrates excellent batch consistency

  • Identity confirmed

    NAD+ identity confirmed by HPLC retention time comparison with reference standard, with chromatogram provided

  • Comprehensive testing panel

    Full QC Panel includes purity, identity, sterility (PCR), endotoxin (USP <85>), and heavy metals (ICP-MS per USP <233>)

  • Complete batch information

    Lot number CRNAD-500-2604-2, COA number COA-2026-WUHSHB, Accession ACC-2026-0953 all clearly documented

  • Appropriate timeline

    Sample received 04/17/2026, analyzed and issued 04/22/2026 (5-day turnaround)

  • ISO/IEC 17025 accredited lab

    ILS Laboratories claims ISO/IEC 17025 accreditation with complete contact information and verification URL provided

  • Professional presentation

    Well-formatted 2-page COA with QR code, chromatogram, conformity testing data, and lab director signature

  • Lab verification recommended

    ILS Laboratories address and accreditation should be independently verified through official ISO/IEC 17025 accreditation body databases
