Public COA audit
PT-141
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 65
- Confidence
- 85%
- Panels
- 1/7
Scored lower because the file is incomplete or not a full COA, limited panel coverage (1/7), 2 critical findings, and notable note: "Heavy metals only report". To improve: upload the full certificate (or the matching sibling purity/endotoxin report) and include identity, purity, and endotoxin at minimum.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
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.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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
Not on this certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
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.”
Purity
Not on this certificate file · core
Reported purity percentage for the analyte.
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.”
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
Pb <0.5 ppm, As <0.15 ppm, Cd <0.05 ppm, Hg <0.3 ppm
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
Sterility
Not on this certificate file
Sterility testing where applicable.
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.”
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.
Heavy metals only report
This is a specialized heavy metals analysis report only. No purity (HPLC), identity (MS/NMR), endotoxin, microbial, sterility, or residual solvent panels are present in this document. This appears to be a supplemental report for one specific test panel.
Heavy metals panel complete
ICP-MS analysis for Pb, As, Cd, Hg with EPA-referenced methods. All elements pass acceptance limits. Spike recovery validation (98%, 102%, 95%, 91%) confirms method suitability. QC controls (method blank, CCV, duplicate RPD <20%) all pass.
Lab identification present
Kovera Labs identified with lab director signature (Lemar Arghandiwal), sample ID KVR-2026-28597D, access code 6E7CCF, and verification URL koveralabs.com/verify.
Batch information present
Lot/Batch PT202605 for PT-141 10mg lyophilized material, client Peptide Partners.
No sample collection date
Analysis date June 13, 2026 is provided, but no sample collection or receipt date is documented.
No purity data in this report
This document is a heavy metals analysis only. A complete COA for research peptides typically requires separate purity/identity testing (HPLC, MS). This may be one component of a multi-report COA package.
