Public COA audit
Retatrutide · Retatrutide 20mg
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 88
- Confidence
- 92%
- Panels
- 2/7
- Purity (printed)
- 99.76%
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).
GLP RT Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.76%
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 purity confirmed
HPLC-UV purity of 99.76% with clear chromatogram showing single major peak at ~15 minutes retention time
Identity confirmed by LC-MS
Mass spectrometry confirmation shows expected GLP RT peaks matching Retatrutide molecular weight profile
Limited testing scope
This COA covers identity and purity only. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing is included in this report
Established testing laboratory
Freedom Diagnostics is a known third-party peptide testing service with verifiable online presence and contact information
Professional presentation
Document includes product photo, clear analytical data, chromatogram, mass spec data, signature, and QR code for verification
Appropriate timeline
Sample received 2026-06-17, reported 2026-06-20 - reasonable 3-day turnaround for identity/purity testing
Batch identification present
Lot number 'Clear Cap/Bronze Crimp' and accession number 2606170094 provided for traceability
