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).

    Epithalon

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.863%

  • Heavy metals

    Tested · passed

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

    As, Cd, Pb, Hg all Negative

  • Microbial

    Tested · passed

    Bioburden / microbial limits testing.

    No Growth

  • Endotoxin

    Tested · passed · core

    LAL or chromogenic endotoxin assay.

    PASS

  • 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

    Batch average purity of 99.863% with consistent individual vial measurements (99.802-99.908%) is normal for research-grade peptides and supported by detailed batch conformity data.

  • Identity confirmed by LC-MS

    Product identity confirmed as Epithalon using LC-MS methodology, matching expected compound.

  • Batch number present

    Batch ET202604 clearly documented with individual vial testing results.

  • Sample date not specified

    Certificate shows issue date (05/13/2026) but does not explicitly state when the sample was collected or received for testing.

  • Lab identification and verification

    Kovera Labs identified with verification URL (koveralabs.com/verify) and access code QLI0IHX. Report number KVR-2026-667A00 provided.

  • Comprehensive testing panels

    Document includes purity (RP-HPLC), identity (LC-MS), heavy metals (4 analytes), endotoxin, and microbial sterility testing. Only residual solvent/water content not explicitly tested.

  • Professional presentation

    Well-formatted COA with clear sections, chromatogram, batch conformity table, product photo, QR code, and lab director signature.

  • Heavy metals method not specified

    Heavy metal screening results provided but analytical method (ICP-MS, ICP-OES, etc.) not documented.
