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).

    Kisspeptin confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.82%

  • 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

    99.82% purity by HPLC is within normal range for research-grade peptides

  • Identity confirmed by mass spectrometry

    LCMS/MS data shows expected mass ions [M+2H]2+ at 651.58 and [M+H]+ at 1302.18/1304.18, consistent with Kisspeptin

  • Limited online presence

    Freedom Diagnostics appears to be a smaller testing facility with minimal verifiable third-party information available online

  • Limited testing scope

    COA only includes identity and purity testing; no heavy metals, microbial, endotoxin, sterility, or residual solvent/water analysis

  • Non-standard presentation

    Document layout and formatting differ from typical commercial analytical lab COAs; includes product photos which is unusual

  • Batch number present

    Lot number KISS08042025-J is clearly stated

  • Dates are reasonable

    Received 8/5/2025, reported 8/6/2025 - one-day turnaround is fast but plausible for identity/purity only
