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).

    Thymosin Beta-4 confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.817%

  • 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

    99.817% purity by HPLC-MS is within normal range for research-grade peptides

  • Identity confirmed with chromatogram

    Mass spec data and chromatogram present showing Thymosin Beta-4 peak

  • Batch/lot number present

    TB1012222025-J clearly stated

  • Dates present and reasonable

    Received 02/23/2026, reported 02/24/2026 - one day turnaround is plausible

  • Lab verification uncertain

    Freedom Diagnostics website and contact provided, but independent verification of lab accreditation/credentials not possible from document alone

  • Limited testing panels

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

  • Non-standard COA format

    Layout and presentation differ from typical third-party analytical lab reports; includes product photos which is unusual for independent testing labs

  • Single signatory

    Only one signature (Stephen Schmidt, Principal Chemist) - many accredited labs use dual review/approval
