Public COA audit
TB-500 · Thymosin Beta-4
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)
- 99.375%
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).
Thymosin Beta-4 confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.375%
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
99.375% purity by HPLC with clean chromatogram showing single major peak at ~8.0 minutes
Mass spectrometry confirmation
Multiple charge states detected ([M+5H]5+, [M+6H]6+, [M+7H]7+, [M+4H]4+) consistent with Thymosin Beta-4 molecular weight
Batch number present
Lot TB1009232025-J clearly stated with net peptide content 10.39 mg
Dates within normal range
Received 9/24/2025, reported 9/25/2025 - one-day turnaround is reasonable for purity/identity testing
Limited lab verification information
Freedom Diagnostics website provided (FreedomDiagnosticsTesting.com) but no physical address, accreditation details, or independent verification of lab credentials visible on this COA
Purity/identity scope only
This COA covers purity and identity testing only. No endotoxin, heavy metals, microbial, sterility, or residual solvent panels present. This is common for basic peptide testing but users should verify if additional safety testing exists separately
Professional presentation
Document includes chromatogram, mass spectrum, product photos, accession number, and searchable verification code
Signatory credentials unclear
Stephen Schmidt listed as Principal Chemist but no professional credentials (PhD, certifications) or license numbers provided
