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.

2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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.

    99.52%

  • 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.

  • High purity confirmed

    UPLC analysis shows 99.52% purity, which is excellent for research-grade NAD+ and consistent with professional synthesis

  • Identity confirmed by UPLC/MS

    Both UPLC chromatogram and MS spectrum provided, showing proper analytical validation with molecular weight ~663.43 g/mol matching NAD+ formula C21H27N7O14P2

  • Clear batch tracking

    Lot number APR-6690114 clearly stated with PubChem CID reference (925)

  • Appropriate timeline

    Received 2026-03-12, analyzed 2026-03-15 - reasonable 3-day turnaround for analytical testing

  • Professional presentation

    Document includes lab branding, analyst signature (Aleksey Yevtodiyenko PhD), contact information, and QR code for validation

  • Limited testing scope

    Only identity and purity panels present. No heavy metals, microbial, endotoxin, sterility, or solvent testing shown. This is common for basic analytical COAs but limits comprehensive quality assessment

  • Professional layout

    Clean, organized format with clear sections, proper scientific notation, and analytical data visualization
