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).

    SS31

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.79%

  • 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 achieved

    99.79% purity exceeds specification of >98%, with clean chromatogram showing single dominant peak

  • Identity confirmed

    Compound identity confirmed as SS31 by LC-MS with mass spectrum showing expected molecular ion peaks

  • Batch/Lot number missing

    The Batch/Lot # field is present but empty, which reduces traceability

  • Reasonable timeline

    8-day turnaround from sample receipt (03/20/25) to analysis completion (03/28/25) is normal for LC-MS testing

  • Lab identification present

    Testing lab BioRegen identified with analyst name (Dr. Roberto Marin), contact email, and verification URL

  • Limited testing scope

    Only identity and purity panels performed; no heavy metals, microbial, endotoxin, sterility, or solvent/water testing

  • Professional presentation

    Document includes chromatogram, mass spectrum, PubChem reference link, QR code for verification, and analyst signature

Timing & next steps

Practical follow-ups based on document age and gaps.

  • coa age
