Public COA audit
BPC-157 · 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
- 88%
- Panels
- 2/7
- Purity (printed)
- 99.44%
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).
BPC-157/Thymosin Beta-4 confirmed by mass spectrometry with peaks at m/z 710.33 [M+2H]2+, 991.43 [M+5H]5+, 1241.33 [M+4H]4+, 1419.38 [M+H]+
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.44%
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
99.44% purity by HPLC is within normal range for research-grade peptides and is supported by clean chromatogram showing two distinct peaks for the two-peptide blend.
Mass spectrometry confirmation
Mass spec data shows expected molecular ion peaks for both BPC-157 and TB-4/Thymosin Beta-4, with multiple charge states visible (M+H, M+2H, M+4H, M+5H), consistent with authentic peptide identification.
Lot number present
Batch lot BPCTB410082025-04 is clearly stated and includes date encoding consistent with 2025 production.
Dates are valid
Received 2025-10-10, reported 2025-10-12 (2-day turnaround). Both dates are before the current date of 2026-09-05 and represent reasonable testing timeline.
Limited lab verification information
Freedom Diagnostics provides a website (FreedomDiagnosticsTesting.com) and email ([email protected]) but no physical address, accreditation information (ISO, GMP, etc.), or independent third-party verification. The lab claims to be 'Proudly Owned and Operated in the USA' but provides minimal credentials.
Limited testing scope
This COA only covers identity and purity testing. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is included. This is a purity/identity-scoped report only and does not represent comprehensive safety testing.
Professional presentation
Document includes chromatogram, mass spectrum, product photos, accession number, search code for verification, and signature of Principal Chemist Stephen Schmidt. Layout is clean and organized.
Research use disclaimer
Document explicitly states peptides are 'intended for research use only and are not approved for human or veterinary use, diagnostic, therapeutic, or clinical applications.' Standard disclaimer but worth noting for end-use context.
