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
- 92
- Confidence
- 88%
- Panels
- 2/7
- Purity (printed)
- 99.873%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), and 2 soft concerns. 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 · 2 passed · 0 failed · 0 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 · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
RT match 1.00, Spectral match 1000
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.873% (average across 4 vials: 99.873%, 99.897%, 99.871%, 99.899%)
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.
High purity confirmed across multiple vials
Four vials tested with purity ranging 99.871-99.899%, consistent and within normal range for research-grade peptides
Dual identity confirmation
Identity confirmed by both retention time (RT=1.00) and spectral match (1000) for all four vials
Client batch number present
Client SID TZ202603 clearly documented
Issue date documented
Published 2026-03-27, which is before the current date (2026-09-05)

Limited scope - purity and identity only
This COA covers purity and identity testing only. No endotoxin, heavy metals, microbial, sterility, or residual solvent testing shown in this report. This is a purity/identity-scoped COA and does not indicate whether additional testing was performed separately.
Professional presentation with photo attachment
Document includes QR code, dual signatures (President and Managing Director), and photo attachment of tested vials
Sample receipt/collection date not stated
No explicit sample receipt or collection date documented, only publication date
