Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 88%
- Panels
- 6/7
- Purity (printed)
- 99.356%
Scored high because the document is mostly consistent but carries soft concerns, broad panel coverage (6/7), and 1 soft concern.

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.
6 of 7 present · 6 passed · 0 failed · 0 reported · 1 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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.356%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As, Cd, Pb, Hg all Negative
Microbial
Tested · passed
Bioburden / microbial limits testing.
No microbial growth detected
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (≤0.5 EU/mL)
Sterility
Tested · passed
Sterility testing where applicable.
No microbial growth detected
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 achieved
Batch average purity of 99.356% with consistent results across 5 vials (range 99.111-99.549%). This is normal for research-grade peptides.
Identity confirmed
LC-MS confirmation matches expected compound (Retatrutide).
Comprehensive testing panel
Includes purity (HPLC), identity (LC-MS), endotoxin, sterility, heavy metals, and fentanyl screening. Missing only residual solvent/water content.
Batch conformity documented
Individual vial testing results provided with consistent purity and net content values.
Issue date valid
Certificate issued 2026-06-12, which is before the current date (2026-09-05).
Lab identification present
Kovera Labs identified with verification URL (koveralabs.com/verify) and access code MGKUXGR.
Professional presentation
Well-structured COA with clear sections, chromatogram, vial photo, QR code, and lab director signature.
Sample date not specified
No explicit sample collection or receipt date provided, only certification date.
