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).

    GLP TZ confirmed via mass spec [M+4H]4+ 1204.20, [M+3H]3+ 1605.55

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.714%

  • 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

    99.714% purity by HPLC is within normal range for research-grade peptides

  • Mass spec confirmation present

    Mass spectrometry data shows expected charge states for tirzepatide with m/z values consistent with the compound

  • Lab verification uncertain

    Freedom Diagnostics and FreedomDiagnosticsTesting.com domain cannot be independently verified as an established testing laboratory

  • Professional presentation inconsistencies

    Document has some formatting irregularities including repeated 'TEST' placeholders in header and inconsistent date format (04/7/2026 vs 04/06/2026)

  • Limited testing scope

    Only identity and purity panels present; no heavy metals, microbial, endotoxin, sterility, or residual solvent testing reported

  • Batch information present

    Lot number 665394 clearly stated with net peptide content of 11.64 mg

  • Dates within acceptable range

    Received 2026-04-06, reported 2026-04-07 (one-day turnaround, both dates are before today 2026-07-28)
