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.

5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).

    Confirmed

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.95%

  • Heavy metals

    Tested · passed

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

    All Not Detected (As, Cd, Cr, Hg, Pb)

  • 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

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    NMT 0.05 EU/mL

  • Sterility

    Tested · passed

    Sterility testing where applicable.

    No Growth

  • 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.

  • High HPLC purity with conformity testing

    99.95% purity confirmed across 3 samples (99.93-99.97% range, mean 99.95%, std dev 0.0163%). This is normal for research peptides and supported by conformity data.

  • Identity confirmed by HPLC

    Double Agonist confirmed by chromatographic retention time comparison with reference standard. Chromatogram shows single clean peak.

  • Batch information complete

    Lot CRTZ-30-2604-1, COA COA-2026-FIVDUT, Accession ACC-2026-0937. Net peptide content 31.48 mg (labeled 30mg).

  • Dates are consistent and valid

    Received 04/17/2026, analyzed 04/22/2026, issued 04/22/2026. All dates are on or before 2026-09-05 and show logical sequence.

  • Lab information and verification provided

    ILS Laboratories, San Diego CA. ISO/IEC 17025 accredited. Verification URL and QR code provided. Access code FMR14LT5.

  • Comprehensive testing panel

    Full QC Panel includes purity (HPLC), identity, sterility (PCR), endotoxin (USP <85>), and heavy metals (ICP-MS). Missing only microbial count and residual solvents/water.

  • Microbial count panel not present

    Sterility testing (PCR) is present, but traditional microbial enumeration (TAMC/TYMC) is not documented.

  • Residual solvents/water content not tested

    No Karl Fischer water content or residual solvent analysis documented.

  • Professional formatting and completeness

    Two-page report with clear tables, chromatogram, conformity testing results, lab director signature, and ISO accreditation statement.
