Public COA audit
Tirzepatide · GLP TZ
Audited September 5, 2026
Multiple signals on this document conflict with known lab formats or verification patterns.
- Legitimacy
- 15
- Confidence
- 92%
- Panels
- 3/7
- Purity (printed)
- 99.784%
Scored poorly because audit signals point to fabrication or reused paperwork, limited panel coverage (3/7), 4 critical findings, and notable note: "Non-existent testing laboratory". To improve: replace this file with an original lab certificate that verifies on the lab portal 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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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).
GLP TZ confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.784%
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (Replicate 1 and 2)
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.
Non-existent testing laboratory
Freedom Diagnostics does not appear to be a legitimate analytical testing laboratory. The website FreedomDiagnosticsTesting.com does not resolve to a known analytical chemistry lab. No accreditation information (ISO 17025, GMP, etc.) is provided.
Unprofessional document design
The COA uses consumer-grade design elements including a stock photo of a vial with printed label, inconsistent formatting, and lacks professional laboratory report structure. Legitimate analytical labs use standardized, professional templates.
Abbreviated compound naming
The compound is listed as 'GLP TZ' rather than the full chemical name 'Tirzepatide' or proper IUPAC nomenclature. Professional COAs typically use complete chemical identifiers.
Missing critical safety panels
No heavy metals, microbial contamination, sterility, or residual solvent/water content testing is documented. Comprehensive peptide analysis typically includes these panels.
Missing accreditation and quality statements
No ISO 17025 accreditation, laboratory certifications, or quality assurance statements are present. The disclaimer focuses on limiting liability rather than affirming analytical standards.
Product photo inclusion
The inclusion of a product vial photograph is highly unusual for analytical COAs, which typically only show analytical data and chromatograms. This suggests a marketing document rather than a laboratory report.
Very rapid turnaround
Sample received 03/10/2026 and reported 03/11/2026 represents a 1-day turnaround for HPLC-MS and endotoxin testing, which is unusually fast for comprehensive analysis.
