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).

    Retention Time 0.5-1 min

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.5%

  • 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

    99.5% purity by R-HPLC is within normal range for research peptides

  • Identity confirmed

    R-HPLC retention time match to analytical standard

  • Batch number present

    PPA-WL-KLOW-P000630

  • Dates present and logical

    Sample received 2026-07-13, analyzed and issued 2026-07-27 (14-day turnaround)

  • Lab verification not possible

    Pacific Coast Biologics Inc - no verification URL provided, cannot independently confirm lab existence or accreditation

  • Limited testing scope

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

  • Multi-compound blend

    Product 'KLOW' contains 4 separate peptides (GHK-Cu, KPV, BPC-157, TB500) with individual quantification. TB500 result (22.5mg) significantly exceeds specification (10mg) by 125%, which is unusual

  • TB500 quantification anomaly

    TB500 measured at 22.5mg against 10mg specification (225% of target) while other compounds are within 10% of target. This large deviation warrants explanation
