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

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.393%

  • 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.

    Replicate 1: PASS, Replicate 2: PASS

  • 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

    99.393% purity is within normal range for research peptides and supported by HPLC-MS data

  • Mass spec confirmation present

    Chromatogram and mass spectrum showing expected molecular ions for both peptides

  • Batch number present

    Lot BPTB20-032026-1 clearly stated

  • Dates within normal range

    Received 2026-03-19, reported 2026-03-21 (2-day turnaround is reasonable)

  • Lab verification uncertain

    Freedom Diagnostics website and contact provided but independent verification not performed; lab appears less established than major third-party testing facilities

  • Limited testing panels

    Only purity, identity, and endotoxin tested; missing heavy metals, microbial, sterility, and residual solvent/water content panels

  • Non-standard COA format

    Layout and presentation differ from established third-party labs (e.g., Janoshik, ChemTox); includes product photo which is unusual for analytical COAs

  • Signatory credentials unclear

    Alex Johnson listed as Principal Chemist but no credentials, certifications, or lab accreditations (ISO, GMP) mentioned
