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).

    MOTS-c confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.28%

  • 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 99.28% purity, which is excellent for research-grade peptides

  • Identity confirmed by UPLC/MS

    Both UPLC chromatogram and MS spectrum provided, showing expected molecular weight and retention time

  • Complete batch information

    Lot number APR-8553761 clearly stated with CAS number 1627580-64-6 and PubChem CID 255386757

  • Recent analysis with appropriate timeline

    Received 2026-03-15, analyzed 2026-03-22 - 7-day turnaround is reasonable

  • Professional laboratory presentation

    Horizon Analytical with contact information, analyst signature (Aleksey Yevtodiyenko PhD), and QR code for validation

  • Limited testing scope

    Only identity and purity panels present. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing shown

  • Professional document structure

    Clean layout with clear sections, chromatograms, mass spectrum, and proper labeling throughout
