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).

    PT-141

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.67%

  • 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.

    Pass (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

    HPLC-UV purity of 99.67% is within normal range for research peptides and supported by clean chromatogram showing single dominant peak

  • Identity confirmed by LC-MS

    Mass spectrometry data provided showing PT-141 molecular ion peaks consistent with bremelanotide structure

  • Batch information present

    Lot number PT10-052026-7 clearly stated with accession number 2605120115

  • Dates within normal range

    Received 2026-05-12, reported 2026-05-14 (2-day turnaround is reasonable)

  • Lab verification unclear

    Freedom Diagnostics Testing website and contact provided, but no independent accreditation numbers (ISO, GMP, etc.) visible on document

  • Limited testing panel

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

  • Generic presentation

    Document layout is clean but relatively simple; lacks detailed lab credentials, QA signatures, or chain-of-custody information typical of higher-tier testing facilities

  • Appropriate disclaimers

    Contains standard research-use-only disclaimer and scope limitations appropriate for peptide testing
