Public COA audit
Double Agonist · 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
- 3/7
- Purity (printed)
- 99.9%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 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.
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).
Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.90%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All Not Detected
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 HPLC purity
99.90% purity by HPLC is excellent and typical for research-grade peptides. Clean chromatogram with single dominant peak.
Identity confirmed
Tirzepatide identity confirmed by HPLC-RTM method.
Fentanyl screening included
Immunoassay fentanyl screen performed with 50 ng/mL cutoff, not detected. This is a valuable safety test.
Heavy metals panel complete
ICP-MS testing for As, Cd, Pb, Hg, Cr all passed (not detected).
Verification URL provided
QR code and verification URL (portal.ils-lab.com/verify/...) present for independent verification.
Batch information complete
Lot number PR-TRZ10-B1-0626-1, accession ACC-2026-8267, labeled content 10mg.
Dates consistent
Date received 2026-07-06, analysis date 2026-07-24, issued 2026-07-24. All dates are logical and sequential.
Endotoxin panel not present
This report does not include endotoxin testing. For injectable peptides, endotoxin testing is typically recommended. This may be a purity/identity-scoped report; endotoxin may have been tested separately.
Microbial and sterility panels absent
No microbial contamination or sterility testing shown on this report. These may be tested separately or not required for this product type.
Professional presentation
Document is well-formatted with clear tables, chromatogram, lab accreditation logos (ISO/IEC 17025, FDA GMP), and signature of Lab Director Dr. Greg Kalyuzhny.
