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.

    18.7 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 achieved

    99.8% purity meets specification of ≥98%, which is normal for research-grade peptides

  • FTIR confirmation with excipients noted

    FTIR spectrum confirms TB-500 presence with excipients/fillers, consistent with formulated product

  • Potency significantly exceeds specification

    HPLC potency results show 122-138% of labeled 10mg (12.2-13.8mg actual), exceeding the 90-110% specification range. This indicates overfilling or labeling discrepancy.

  • Batch/lot number clearly stated

    Lot CR-TB510-2603-1 consistently referenced across all three report pages

  • Testing dates are recent and logical

    Sample tested 4/2/2026, report issued 4/5/2026, endotoxin test 4/8/2026 with report 4/10/2026 - all dates are sequential and reasonable

  • Lab information provided

    BTLabs, West Palm Beach FL with contact details and website. Dual scientist signatures present on all pages.

  • Limited testing scope

    Testing purpose explicitly states it does NOT provide information on particulate matter or microbial contamination. Heavy metals, sterility, and residual solvents not tested. Only identity, purity, potency, and endotoxin panels performed.

  • Professional presentation with supporting data

    Report includes FTIR spectrum, HPLC chromatogram, detailed peak data, QR code, and product photo. Multi-page format with consistent headers and report numbers.

  • Endotoxin testing performed separately

    Dedicated endotoxin test report (page 3) shows PASS result at 18.7 EU/vial against 40 EU/vial limit
