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.

3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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).

    GLP RT confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.94% average (Vial 1: 99.98%, Vial 2: 99.94%, Vial 3: 99.91%)

  • 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

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    ≤ 0.05 EU/mL (both replicates)

  • 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

    Average purity of 99.94% across three vials is consistent with high-quality research peptide synthesis. Individual vial purities range from 99.91% to 99.98%.

  • Mass spec confirmation present

    Mass spectrometry data shows [M+3H]3+ and [M+4H]4+ peaks consistent with peptide identification. Chromatogram shows single dominant peak.

  • Limited testing panels

    Only purity, identity, and endotoxin testing performed. Missing heavy metals, microbial, sterility, and residual solvent/water analysis. This is common for basic research peptide COAs but limits comprehensive quality assessment.

  • Limited lab verification information

    Freedom Diagnostics website and contact provided, but no accreditation information (ISO, GMP, etc.) visible on COA. Lab claims USA operation but no specific address or regulatory credentials shown.

  • Batch information complete

    Lot number CRRT-15-0126-01 clearly stated with individual vial content measurements (15.53 mg, 15.02 mg, 15.27 mg).

  • Dates are reasonable

    Received 2026-01-08, reported 2026-01-11 (3-day turnaround). Both dates are in the past relative to current date 2026-07-28.

  • Professional presentation

    Document includes company branding, chromatogram, mass spec data, product photos, and chemist signature. Layout is organized and includes appropriate disclaimers for research use only.
