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.

    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.
