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
- 92
- Confidence
- 93%
- Panels
- 4/7
- Purity (printed)
- 99.9%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (4/7), 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.
4 of 7 present · 4 passed · 0 failed · 0 reported · 3 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
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All ND (As, Cd, Pb, Hg)
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.
ND (LOQ 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 min retention time
Mass spectral confirmation
Mass spectrum shows expected charge states (m/z 1579.1, 1184.4) consistent with Retatrutide molecular weight; ID confirmed by comparison to authentic standard
Batch/lot number present
Lot hqrz3hn clearly stated with verification URL provided
Date sequence logical
Sample received 6/30/2026, testing performed 7/5-7/15/2026, report issued 7/20/2026 - all dates are sequential and reasonable
Established testing laboratory
Krause Analytical LLC is a known third-party peptide testing lab in Austin, TX; report includes lab director signature and detailed methods summary
Comprehensive testing panel
Includes purity, identity, endotoxin, and FDA critical metals (As, Cd, Pb, Hg) - all with appropriate USP methods
Professional formatting
Multi-page report with chromatogram, mass spectrum, methods summary, and proper footer/header branding consistent with Krause Analytical and Finnrick vendor
Microbial and sterility panels not included
No microbial count or sterility testing shown; this is common for research-grade peptides but worth noting for applications requiring sterility
