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
- 72
- Confidence
- 85%
- Panels
- 2/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 2 soft concerns, and notable note: "Identity confirmation via UPLC and MS". 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 · 0 passed · 0 failed · 2 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).
MS2 ES+ TIC 2.7427, MS2 ES+ TIC 4.7148, MS2 ES- 7.2265
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
UPLC chromatogram shown, no numeric purity stated
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 confirmation via UPLC and MS
Document shows UPLC chromatograms and mass spectrometry data. MS spectrum shows expected molecular ion region around m/z 1602-1604 with charge state peaks consistent with Tirzepatide. PubChem CID 156588324 is referenced.
Purity/identity report file
This certificate file looks like a purity/identity report. Many vendors publish a separate endotoxin report for the same lot — missing endotoxin on this file alone does not prove the lot was never tested.
Lot number clearly stated
Lot Number APR-8791503 is clearly printed at top of document.
Dates are reasonable and consistent
Received Date: 03/20/2026, Analysis Conducted: 03/27/2026. Both dates are in the past relative to today (2026-09-05) and show a 7-day turnaround, which is plausible for analytical testing.
Lab verification not independently confirmed
Horizon Analytical is listed with contact email [email protected] and searchable via horizonanalytical.com. The document appears professionally formatted, but independent verification of this lab's existence and accreditation was not performed in this audit.
Professional presentation
Document has clean layout, branded header, clear chromatograms and mass spectrum. Formatting is consistent with a legitimate analytical lab report.
