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.

1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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).

    TB-500 (TB4) identified along with mannitol and degradation products

  • Purity

    Not on this COA · core

    Reported purity percentage for the analyte.

    No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.

  • 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.

  • No purity quantification

    This report is labeled as a contamination screening test only. No HPLC purity percentage is provided, which is essential for a complete COA for research peptides.

  • Degradation products detected

    LCMS analysis identified degradation products alongside TB-500, which may indicate storage or handling issues, though no quantification of degradation is provided.

  • Limited testing scope

    Only LCMS contamination screening was performed. No purity quantification, heavy metals, microbial, endotoxin, sterility, or residual solvent testing is included.

  • Batch number present

    Batch Test-CY3 is clearly identified.

  • Known testing lab

    Janoshik is a recognized third-party testing laboratory for research compounds. Verification URL and unique key (AWP2R8UR5S57) are provided.

  • Professional presentation

    Report includes chromatogram and mass spectra data from Shimadzu LabSolutions, consistent with legitimate analytical output.
