Public COA audit
Retatrutide
Audited September 5, 2026
Document structure and test panels align with what we expect from authentic lab reports.
- Legitimacy
- 95
- Confidence
- 95%
- Panels
- 3/7
- Purity (printed)
- 99.04%
Scored high because document structure and panels look consistent with authentic lab output and limited panel coverage (3/7). 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).
Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.04%
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.
0.055 EU/mL
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
99.04% peptide purity by HPLC meets ≥95.0% specification. This is normal for research-grade peptides.
Identity confirmed
Retatrutide confirmed by HPLC retention time match with reference standard. Fentanyl screen negative.
Batch information present
Lot Number: Blue Cap, COA #: COA-2026-KLHVNE, Accession #: ACC-2026-3383
Dates consistent
Sample received 2026-05-27, analyzed and issued 2026-06-05. All dates are valid and sequential.
Lab credentials present
ILS Laboratories, San Diego CA. ISO/IEC 17025 accredited. Verification URL and QR code provided. Lab director signature present.
Core panels complete
Identity, purity, and endotoxin testing performed. Heavy metals, microbial, sterility, and residual solvent panels not included in this report scope.
Endotoxin testing included
Endotoxin result 0.055 EU/mL by USP <85> kinetic turbidimetric method. Report notes this is below commonly referenced thresholds for RUO products.
Professional presentation
Document includes HPLC chromatogram, detailed methodology notes, QR verification code, and clear pass/fail indicators. Formatting consistent with legitimate analytical lab reports.
