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
- 3/7
- Purity (printed)
- 99.9%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 4 soft concerns, and notable note: "High purity confirmed". 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.
3 of 7 present · 2 passed · 0 failed · 1 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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.9%
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 · result on file · core
LAL or chromogenic endotoxin assay.
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.
High purity confirmed
Chromatographic purity >99.9% by HPLC-UV/MS with clean chromatogram showing single dominant peak at 6.70 min
Identity confirmed by mass spectrometry
Mass spectrum matches reference standard for Tirzepatide (CAS 2023788-19-2)
Batch/lot number present
Lot j9f35yh clearly marked on certificate and vial images
Dates are consistent and valid
Sample received 2/6/2026, tested 2/14/2026, report issued 2/20/2026 - all dates are logical and on or before 2026-09-05
Branding inconsistency
Document shows dual branding: 'Finnrick' (header, URL, vial label) and 'Krause Analytical LLC' (footer, signature, methods). This may indicate a vendor/lab partnership or white-labeling arrangement, but creates ambiguity about the actual testing entity.
Verification URL domain mismatch
Verification URL is https://finnrick.com/verify but lab entity is Krause Analytical LLC. Domain ownership and verification system authenticity cannot be confirmed from document alone.
Methods described but results not shown
Page 3 describes methods for Endotoxins (USP/NF 85, LAL) and Metals (USP/NF 233, ICP-MS), but no actual test results are provided in this certificate. This may be a purity/identity-scoped report only.
Limited testing scope
Only purity and identity testing results are shown. No microbial, sterility, residual solvent, or water content testing present. Endotoxin and heavy metals methods are described but not executed/reported in this document.
Professional presentation
Document includes chromatogram, mass spectrum comparison, detailed methods, vial photos, and proper scientific notation. Layout is consistent with legitimate analytical lab reports.
