Public COA audit
Glutathione
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 2/7
- Purity (printed)
- 99.73%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "High purity confirmed". 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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
Glutathione confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.73%
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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
99.73% purity by HPLC-MS is excellent and typical for research-grade glutathione
Identity confirmed
Mass spectrometry shows expected [M+H]+ peak at 308.00 m/z consistent with glutathione, HPLC chromatogram shows single major peak
Batch number present
Lot 25042801-H clearly documented
Dates reasonable
Received 2025-07-22, reported 2025-07-23 (1-day turnaround is fast but plausible for purity/identity-only testing)
Lab verification unclear
Freedom Diagnostics claims USA operation with website FreedomDiagnosticsTesting.com and email [email protected], but independent verification of this lab's accreditation/reputation is recommended
Limited scope - purity/identity only
This COA covers purity and identity testing only. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water panels are present. This is a purity/identity-scoped report and does not indicate whether the vendor has conducted additional safety testing on this lot
Minor formatting inconsistencies
Document shows 'Assession Number' (likely typo for 'Accession'), and some text fields show 'TEST TEST TEST' placeholders, suggesting template-based generation
Timing & next steps
Practical follow-ups based on document age and gaps.
