Public COA audit
PT-141
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 88%
- Panels
- 2/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "Sterility-only report". To improve: include identity, purity, and endotoxin at minimum and prefer labs with a public verification portal.

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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar 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.”
Microbial
Tested · passed
Bioburden / microbial limits testing.
No microbial growth detected; Fungi/Yeast Not Detected
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
Tested · passed
Sterility testing where applicable.
No microbial growth detected
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.
Sterility-only report
This is a sterility screening report only. No purity, identity, endotoxin, heavy metals, or residual solvent testing is included. This is a partial COA and should be accompanied by other analytical reports for complete quality assessment.
Rapid screening method
Document explicitly states this is a 'rapid screening method' (2-day incubation) suitable for quality control but notes that 'for regulatory compliance, full compendial sterility testing may be required.' This is a preliminary assessment, not a full USP <71> sterility test.
Lab verification needed
Kovera Labs is not a widely recognized third-party testing laboratory in the peptide industry. No verification URL or independent contact information is provided. The QR code and access code (28597D) suggest a verification system exists but cannot be validated from this document alone.
Same-day turnaround
Sample received and certified on the same date (06/12/2026). While rapid for sterility screening, this is plausible for a 2-day rapid method if the report generation occurred after the incubation period.
Batch information present
Lot number PT202605 is clearly stated and appears consistent with a May 2026 production date format.
Professional presentation
Document has professional formatting with clear sections, consistent branding, and appropriate technical language for a sterility screening report.
