Public COA audit
Retatrutide
Audited September 5, 2026
Document structure and test panels align with what we expect from authentic lab reports.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 3/7
- Purity (printed)
- 99.9%
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 · 3 passed · 0 failed · 0 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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.9%
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 · passed · core
LAL or chromogenic endotoxin assay.
<0.5 EU
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.
Excellent chromatographic purity
HPLC purity >99.9% with clean chromatogram showing single dominant peak at ~7 minutes retention time
Mass spectral confirmation
Mass spectrum shows expected m/z peaks (1586.5, 1585.7, 1195.7) consistent with Retatrutide molecular weight and charge states
Batch information complete
Lot 38h96wg, Lab# 206878, Project 145306, 30mg label claim with 27.5mg recovered (91.8% of label)
Timeline appropriate
Sample received 2026-06-09, testing performed 2026-06-11 to 2026-06-14, report issued 2026-06-16 - all dates are sequential and reasonable
