Audited September 5, 2026
Document structure and test panels align with what we expect from authentic lab reports.
- Legitimacy
- 95
- Confidence
- 95%
- Panels
- 5/7
- Purity (printed)
- 99.62%
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).
Confirmed (Retatrutide)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.62%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.335 ppm, Cd: 0.1006 ppm, Pb: 0.1005 ppm, Hg: 0.1087 ppm, Cr: 0.1387 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.
NMT 0.05 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 with conformity testing
99.62% purity confirmed across 3 samples (mean 99.43%, std dev 0.1349%). Includes representative chromatogram and detailed methodology.
Identity confirmed by HPLC-RTM
Compound confirmed as Retatrutide (GLP-3 RT) by chromatographic retention time comparison with reference standard.
Comprehensive testing panel
Includes purity/quantitation (HPLC), identity (HPLC-RTM), heavy metals (ICP-MS), sterility (PCR), and endotoxin (USP <85>). All tests passed.
Clear batch identification
Lot RT10-655, COA COA-2026-R9UV-W, Accession ACC-2026-6114. Net peptide content 10.55 mg (labeled 10 mg).
Appropriate timeline
Received 2026-06-22, analyzed 2026-07-01, issued 2026-07-01. 9-day turnaround is reasonable for comprehensive testing.
ISO/IEC 17025 accredited lab
ILS Laboratories, San Diego, CA. ISO/IEC 17025 accredited. Includes verification URL, access code, and QR code for authentication.
Professional presentation
Well-formatted 2-page report with detailed methodology notes, conformity testing results table, chromatogram, and proper signatures/accreditation marks.
