Public COA audit
Tirzepatide
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 68
- Confidence
- 82%
- Panels
- 2/7
- Purity (printed)
- 96.89%
Scored lower because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 5 soft concerns, and notable note: "Identity result unclear". To improve: 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.
2 of 7 present · 1 passed · 0 failed · 1 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
Tested · result on file · core
Compound identity confirmed (e.g. HPLC, mass spec).
24.82 mg
Purity
Tested · passed · core
Reported purity percentage for the analyte.
96.89%
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
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.
Identity result unclear
Identity section shows '24.82 mg' which appears to be peptide content/mass rather than molecular weight confirmation. LC-MS is mentioned in methods but no m/z or molecular weight value is provided.
No batch/lot number
Batch field explicitly states 'Unidentified', making traceability and repeat verification difficult
Unusual timeline
Testing ordered 10 APR '26, sample received 25 MAY '26 (45 days later), analysis conducted 29 MAY '26. The long gap between order and receipt is unusual but not impossible for international shipping.
Limited lab verification
Axiom Analytics (axiomanalytics.cz) provides verification URL but lab's online presence and accreditation status cannot be confirmed from this document alone
Limited scope testing
This report covers only purity and identity. No heavy metals, microbial, endotoxin, sterility, or water content testing shown. Document states 'Standard peptide analysis' was requested, which may explain limited scope.
Professional presentation
Document has consistent formatting, QR code, verification key, signature, and clear specification/status indicators
HPLC purity within specification
96.89% purity meets >=95.0% specification via RP-HPLC
