Retatrutide
Audited September 9, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 7/7
- Purity (printed)
- 99.2%
Scored moderately because the document is mostly consistent but carries soft concerns, broad panel coverage (7/7), 3 soft concerns, and notable note: "High HPLC purity". To improve: prefer labs with a public verification portal.

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.
7 of 7 present · 7 passed · 0 failed · 0 reported · 0 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).
Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.2%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
N.D.
Microbial
Tested · passed
Bioburden / microbial limits testing.
N.D.
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
<0.1 EU/mg
Sterility
Tested · passed
Sterility testing where applicable.
Sterile
Residual solvent / water
Tested · passed
Residual solvents or water content limits.
3.8%
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 HPLC purity
99.2% purity by HPLC is within normal range for research-grade peptides
Identity confirmed
HPLC identity test shows confirmed result
Comprehensive testing
All seven major panel types present: identity, purity, heavy metals, microbial, endotoxin, sterility, and residual solvent/water
Batch number present
Lot No: RET-26080201
Dates present and valid
Test Date and Retest Date both June 2, 2026, which is before the current date of September 9, 2026
Lab verification not possible
Golden Age Pharmaceutical is listed as the testing lab, but no website URL, contact information, or third-party verification method is provided on this COA
Generic template appearance
The COA uses a generic template design with stock certification badges (GMP, ISO, LAB TESTED, COA) that are common across many vendors and do not provide independent verification
Quality Control Director signature
Approval section shows Quality Control Director name (Zhang Hua) and date (June 2, 2026) but no actual signature or stamp is visible
