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).

    FTIR sample spectrum confirms the presence of TB-500 with addition of excipient(s)/fillers

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.8%

  • 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.

    18.3 EU/vial (limit: 40 EU/vial)

  • 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 HPLC purity confirmed

    HPLC purity of 99.8% meets specification (≥98%). This is normal for research-grade peptides.

  • Identity confirmed by FTIR and HPLC

    FTIR spectrum confirms TB-500 presence with excipients/fillers. HPLC chromatogram shows single dominant peak.

  • Potency exceeds labeled amount

    HPLC potency assay shows 115.5-141.1% of labeled 10mg content across three measurements. While within some industry tolerances, this is notably above the 90-110% specification range stated on the COA.

  • Label discrepancy noted

    Visual description states vial is 'Labeled as: BPC-500_TB-500' but testing material is TB-500. This dual-label notation is unusual and may indicate co-formulation or labeling inconsistency.

  • Dates are consistent and valid

    Sample tested 4/2/2026, COA issued 4/5/2026, endotoxin test dated 4/8-4/10/2026. All dates are sequential and on or before today (2026-07-28).

  • Lab information provided

    BTLabs, West Palm Beach FL. Contact info and website provided. Lab uses USP methods and provides detailed analytical data including FTIR spectra and HPLC chromatograms.

  • Limited safety panel coverage

    COA includes identity, purity, and endotoxin testing. Missing: heavy metals, microbial contamination (beyond endotoxins), sterility, and residual solvents/water content. The COA explicitly states it 'does not provide information on particulate matter, microbial contamination or presence of endotoxins' on page 1, but page 3 does include endotoxin testing.

  • Professional presentation with supporting data

    Multi-page COA with detailed analytical graphs (FTIR, HPLC), QR code, dual scientist signatures, report numbers, and revision tracking (Rev 1.0 January 2025).
