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
- 3/7
- Purity (printed)
- 99.18%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 3 soft concerns, and notable note: "High HPLC purity". 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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.18%
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.
<0.5 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.
High HPLC purity
99.18% chromatographic purity is excellent and normal for research-grade glutathione
Mass spectral confirmation
Identity confirmed by HPLC-UV-MS with reference spectrum match shown on page 2
Batch/lot number present
Lot g8k5ahp clearly marked with vial photos showing matching lot number
Dates are valid
Sample received 2026-02-26, testing completed 2026-02-28 to 2026-03-03, all dates are on or before 2026-09-05
Lab name discrepancy
Document header shows 'Finnrick Analytics' and 'Finnrick.com' but footer and signature reference 'Krause Analytical LLC' - appears to be a vendor/reseller (Finnrick) using contract lab (Krause) services, which is common but creates potential confusion
Verification URL domain mismatch
Verification URL is https://finnrick.com/verify but testing lab is Krause Analytical - verification should ideally be through the testing lab's domain
Heavy metals method described but not tested
Page 3 describes USP/NF 233 ICP-MS method for metals testing, but no results appear in the COA - method may be available but not performed for this sample
Endotoxin testing present
Endotoxin testing performed via USP 86 LAL method with result <0.5 EU, passing specification
Professional presentation
Multi-page report with chromatogram, mass spectrum, methods summary, and vial photos - consistent with legitimate analytical lab format
