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).

    BPC-157/Thymosin Beta-4 confirmed by mass spectrometry

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.93%

  • 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

    99.93% purity by HPLC-UV with mass spectrometry confirmation. This is normal for research-grade peptides.

  • Identity confirmed by MS

    Mass spectrometry data shows expected molecular ion peaks for both BPC-157 and TB-4 with charge states labeled.

  • Batch/lot number present

    Lot 0008 clearly stated on both pages.

  • Lab verification limited

    Freedom Diagnostics claims USA operation and provides a website (FreedomDiagnosticsTesting.com) and email. However, independent verification of this lab's accreditation, history, or third-party recognition is not provided on the COA itself. The lab name and branding appear professional but lack external validation markers (e.g., ISO certification, accreditation body logos).

  • Endotoxin testing performed

    Page 2 shows endotoxin testing per USP <85> in duplicate, both replicates pass at ≤0.05 EU/mL.

  • Missing heavy metals, microbial, sterility, and residual solvent panels

    COA only includes identity, purity, and endotoxin. No heavy metals, microbial contamination, sterility, or residual solvent/water content testing reported. This is not uncommon for research peptide COAs but limits comprehensive quality assurance.

  • Professional presentation

    Document includes chromatogram, mass spectrum, product photos, signatory (Stephen Schmidt, Principal Chemist), and clear disclaimers. Layout is consistent and professional.

  • Two accession numbers for same lot

    Page 1 is accession 2511190037, page 2 is 2511190038, both for lot 0008 received/reported same dates. Page 2 appears to be endotoxin-only supplement. This is unusual but not necessarily fraudulent—may indicate separate test orders or internal lab workflow.
