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).

    MOTS-c

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.964%

  • Heavy metals

    Tested · passed

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

    As <0.11, Cd <0.08, Pb <0.7, Hg <0.2

  • 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.

    PASS (≤ 0.50 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 purity confirmed

    Batch average purity of 99.964% with consistent individual vial results (99.933-99.988%) is excellent and typical for research-grade peptides.

  • Identity confirmed by LC-MS

    MOTS-c identity verified using LC-MS, which is an appropriate method for peptide identification.

  • Batch conformity documented

    Five individual vials tested with detailed purity and net content results showing good batch consistency.

  • Issue date valid

    Certificate issued 2026-04-04, which is before the current date of 2026-09-05.

  • Lab identification present

    Kovera Labs identified with verification URL (koveralabs.com/verify), report number KVR-2026-1E8D20, and access code G423UEK provided.

  • Comprehensive testing panel

    Document includes purity (RP-HPLC), identity (LC-MS), heavy metals screening, bacterial endotoxins (LAL), and full sterility verification.

  • Missing panels

    No microbial contamination panel or residual solvent/water content testing documented in this report.

  • Professional presentation

    Well-formatted document with clear sections, chromatogram included, product photo, QR code for verification, and lab director signature.
