Public COA audit
Retatrutide
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 68
- Confidence
- 82%
- Panels
- 2/7
- Purity (printed)
- 99.767%
Scored lower because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "High purity result". 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).
Retatrutide identified (49.98 mg)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.767%
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 result
99.767% purity is excellent for research peptides and within normal range for quality Retatrutide samples
Identity confirmed via blind test
Sample correctly identified as Retatrutide through GLP-1 peptide blind test panel, with quantified mass of 49.98 mg
Batch/lot number missing
No batch or lot number provided on the report, which limits traceability to the original manufacturer
Dates are valid and logical
Testing ordered 15 JAN 2026, sample received 03 FEB 2026, analysis conducted 06 FEB 2026 - all dates are sequential and on or before today (2026-09-05)
Known testing laboratory
Janoshik Analytical is a recognized third-party testing lab for peptides and performance-enhancing compounds, with verification URL provided
Limited testing scope
This report covers identity and purity only. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing is included. This is common for basic peptide testing but limits safety assessment
Minimal documentation
Sample and Batch fields are blank, manufacturer listed as 'Unknown', and no chromatogram or detailed methodology provided. Report is sparse compared to comprehensive COAs
