Public COA audit
GLP-RT · Reta Peptide
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 85
- Confidence
- 88%
- Panels
- 3/7
- Purity (printed)
- 99.98%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), and 2 soft concerns. 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).
GLP-RT confirmed by mass spectrometry with [M+3H]3+ 1577.33 and [M+3H+K]4+ 1192.88
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.98%
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.
≤ 0.05 EU/mL (both replicates)
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 confirmed
99.98% purity by HPLC is excellent and normal for research-grade peptides. HPLC chromatogram shows single clean peak at ~14 min.
Mass spectrometry confirmation
Identity confirmed by LCMS/MS with appropriate mass peaks for GLP-RT (retatrutide). Mass spectrum shows expected charge states.
Endotoxin testing included
Separate endotoxin report (page 2, accession 2511190034) shows duplicate testing per USP <85>, both replicates pass at ≤ 0.05 EU/mL.
Batch information present
Lot 0010, net peptide content 12.19 mg stated, white lyophilized powder appearance documented with photo.
Lab verification recommended
Freedom Diagnostics claims USA operation with searchable verification at FreedomDiagnosticsTesting.com. Independent verification of lab credentials and accreditation status recommended.
Limited panel scope
This COA covers purity, identity, and endotoxin only. Heavy metals, microbial contamination, sterility, and residual solvents/water content not tested. This is common for basic peptide COAs but limits comprehensive quality assessment.
Professional presentation
Document includes chromatograms, mass spectra, product photo, signatory (Stephen Schmidt, Principal Chemist), and appropriate research-use-only disclaimers.
