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.

6 of 7 present · 6 passed · 0 failed · 0 reported · 1 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).

    Klow

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.607%

  • Heavy metals

    Tested · passed

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

    All Negative (As, Cd, Pb, Hg)

  • Microbial

    Tested · passed

    Bioburden / microbial limits testing.

    No Growth

  • Endotoxin

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    Pass (≤0.5 EU/mL)

  • Sterility

    Tested · passed

    Sterility testing where applicable.

    No Growth

  • 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 purity confirmed

    Blend average purity of 99.607% with consistent vial measurements (99.546%, 99.668%) and supporting chromatogram. This is normal for research-grade peptides.

  • Identity confirmed by LC-MS

    Blend identification performed using LC-MS methodology, industry standard for peptide verification.

  • Comprehensive testing panel

    Document includes purity, identity, endotoxin, fentanyl screening, microbial sterility, heavy metals, and pH testing. Blend component analysis shows measured vs labeled quantities for four peptides.

  • Batch information complete

    Batch number AMC-KLOW-80-01 clearly stated with batch conformity results showing two vial measurements.

  • Issue date valid

    Certificate issued 2026-07-16, which is 13 days before current date (2026-07-29). Recent and valid.

  • Lab identification present

    Kovera Labs identified with verification URL (koveralabs.com/verify), QR code, report number KVR-2026-2BE647, access code 1R268SS, and lab director signature.

  • Professional presentation

    Clean, professional layout with clear tables, chromatogram with method details (RP-HPLC, C18 column, DAD @ 214 nm), product photo, and comprehensive test result documentation.

  • Residual solvent/water content not explicitly tested

    No dedicated residual solvent or water content panel visible, though this is not uncommon for all COAs.
