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
- 93%
- Panels
- 2/7
- Purity (printed)
- 99.09%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), and 1 soft concern. 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).
Tirzepatide confirmed via LC-MS/MS precursor [M+5H]5+ 963.90 Da with MRM transitions
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.09%
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 chromatographic purity
99.09% purity exceeds specification of ≥98%, which is normal and expected for research-grade peptides
Comprehensive identity confirmation
LC-MS/MS with precursor ion and dual MRM transitions (quantifier and qualifier) provides robust identity verification
Label accuracy verified
Net peptide content 10.43 mg vs labeled 10.00 mg gives 104.3% accuracy, exceeding ≥90% specification
Clear batch identification
Sample ID TIR-006 with report number COA-2026-SC-00310
Appropriate timeline
Sample received 2026-07-15, analyzed and reported 2026-07-20 (5-day turnaround)
Professional laboratory presentation
SideChain Analytics with detailed methodology, instrument specifications (Agilent 1290 Infinity II + 6495 QQQ), and appropriate disclaimers
Verification system present
QR code and URL (Peptidetestcanada.ca/verify) with verification code PTC-9QZBS592 provided
Limited scope - purity/identity only
This report covers identity and purity testing only. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing included in this file. This is common for split reports where different panels may be issued separately.
Professional formatting
Well-structured report with clear sections, sample photograph, chromatogram, and technical specifications including CAS number, molecular formula, and molecular weight
