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
- 88%
- 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.
2.5 EU
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 ~7 minutes retention time
Mass spectral identity confirmed
Mass spectrum shows expected m/z peaks (1613.4, 1606.1, 1216.0) consistent with Tirzepatide, ID confirmed by comparison to authentic standard
Batch/lot number present
Lot 2jx3cqq clearly stated with vial photos showing matching lot number on label
Dates within normal range
Sample received 2026-06-04, report issued 2026-06-15, testing dates 2026-06-06 to 2026-06-11 - all dates are consistent and on or before 2026-09-05
Branding inconsistency
Document shows dual branding: header/footer say 'Finnrick Analytics' and 'Finnrick.com' but signature block, methods page, and logo say 'Krause Analytical LLC' at 8127 Mesa Drive Suite B-206 Austin, TX 78759. This appears to be a reseller/white-label arrangement but creates verification ambiguity
Verification URL domain mismatch
Verification URL is https://finnrick.com/verify but the actual testing lab is Krause Analytical LLC. Cannot independently verify if Finnrick is an authorized reseller or if Krause Analytical actually performed this test
Endotoxin testing performed
Endotoxin result 2.5 EU (LOQ 0.5) by USP 86 LAL method on 2026-06-11. No explicit pass/fail stated but value is measurable and method is documented
Heavy metals method listed but no results
Page 4 Methods Summary describes USP/NF 233 ICP-MS method for metals testing, but no metals results appear in the main COA table on page 1
Limited testing scope
No microbial contamination testing, sterility testing, or residual solvent/water content testing performed or reported
Professional presentation
Multi-page report with detailed chromatogram (page 2), mass spectrum (page 3), and methods summary (page 4). Includes vial photos, signature, and standard disclaimers
