Audited September 5, 2026
Document structure and test panels align with what we expect from authentic lab reports.
- Legitimacy
- 95
- Confidence
- 92%
- Panels
- 5/7
- Purity (printed)
- 99.92%
Scored high because document structure and panels look consistent with authentic lab output and broad panel coverage (5/7).

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.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.92%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As 0.687 ppm, Cd 0.3345 ppm, Pb 0.639 ppm, Hg 0.557 ppm, Cr 6.32 ppm
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 · passed · core
LAL or chromogenic endotoxin assay.
0.14 EU/mL
Sterility
Tested · passed
Sterility testing where applicable.
No Growth
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
99.92% purity by HPLC with conformity testing across 3 samples (mean 99.88%, std dev 0.0497%). This is normal for research-grade peptides.
Identity confirmed
Tirzepatide confirmed by HPLC retention time match. Fentanyl screen negative.
