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 KPV 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 achieved

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

  • Identity confirmed by FTIR and HPLC

    FTIR spectrum confirms presence of KPV with excipients/fillers. HPLC chromatogram shows single dominant peak at 1.563 min retention time.

  • Potency below specification range

    HPLC potency assay shows three measurements: 8.2 mg (82.1%), 7.3 mg (73%), and 9.9 mg (98.9%). Two of three measurements fall below the 90-110% specification range for the labeled 10 mg content.

  • Batch/lot number clearly stated

    Lot number CR-KPV10-2603-1 is consistently referenced across all three pages.

  • Testing dates are recent and logical

    Sample tested 4/2/2026, report issued 4/5/2026, endotoxin test dated 4/8/2026 and issued 4/10/2026. All dates are sequential and reasonable.

  • Lab information provided

    BTLabs, West Palm Beach, FL with contact details and website. Two scientists signed (Andrea Castro, AS and Verna Zheng, AS).

  • Limited testing scope

    COA explicitly states it does not provide information on particulate matter, microbial contamination (beyond endotoxins), heavy metals, sterility, or residual solvents. Only identity, purity, potency, and endotoxin testing performed.

  • Professional presentation with supporting data

    Report includes FTIR spectrum, HPLC chromatogram, detailed test results table, QR code, and sample photo. Formatting is consistent with professional lab reports.

  • Mass variability across three measurements

    Three separate mass measurements (55.9 mg, 50.7 mg, 57.4 mg) show significant variation, which may indicate sampling inconsistency or heterogeneous product.
