Public COA audit

BPC 157

Audited September 5, 2026

Incomplete documentation

Missing panels or key metadata — not enough evidence to treat this as a full certificate.

Legitimacy
45
Confidence
75%
Panels
2/7
Purity (printed)
99.45%

Scored poorly because the file is incomplete or not a full COA, limited panel coverage (2/7), 1 critical finding, and notable note: "No lot/batch number". To improve: upload the full certificate (or the matching sibling purity/endotoxin report) and include identity, purity, and endotoxin at minimum.

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 · 0 passed · 0 failed · 2 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 · result on file · core

    Compound identity confirmed (e.g. HPLC, mass spec).

    HPLC chromatogram shown

  • Purity

    Tested · result on file · core

    Reported purity percentage for the analyte.

    99.45%

  • Heavy metals

    Not on this certificate file

    Lead, arsenic, cadmium, mercury, or similar limits.

    No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”

  • Microbial

    Not on this certificate file

    Bioburden / microbial limits testing.

    No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”

  • Endotoxin

    Not on this certificate file · core

    LAL or chromogenic endotoxin assay.

    No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”

  • Sterility

    Not on this certificate file

    Sterility testing where applicable.

    No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”

  • Residual solvent / water

    Not on this certificate file

    Residual solvents or water content limits.

    No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”

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 on this file

Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.

Findings

Evidence-linked observations from this audit.

  • No lot/batch number

    Lot number field shows 'N/A' which is highly unusual for a legitimate COA. Batch traceability is essential for quality control.

  • No sample date

    Only analysis date (2023.08.25) is provided. No sample collection or receipt date documented.

  • Limited testing scope

    This report only covers purity/identity testing. No safety panels (endotoxin, heavy metals, microbial, sterility, residual solvents) are included. This may be a purity-only report with other testing documented separately.

  • High purity result

    99.45% purity by HPLC with clear chromatogram showing main peak at 12.77 min and minor impurities totaling 0.55%.

  • HPLC-MS method documented

    Uses Acquity H-class Plus Xevo G2-XS QTOF, a legitimate high-resolution mass spectrometry system suitable for peptide analysis.

  • Limited lab verification

    Weipu appears to be a Chinese testing laboratory with addresses in Shanghai. Website provided but no accreditation marks (ISO 17025, GMP, etc.) visible on this report.

  • Minimal documentation

    Report lacks standard COA elements: no analyst signature, no QA approval, no specification limits, no pass/fail criteria, no certificate number.

Timing & next steps

Practical follow-ups based on document age and gaps.

  • coa age

    This COA was issued over a year ago (1107 days) — consider whether a retest is warranted for this batch.
