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
- 88
- Confidence
- 92%
- Panels
- 3/7
- Purity (printed)
- 99.93%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), and 1 soft concern. 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).
BPC-157/Thymosin Beta-4 confirmed by mass spectrometry with m/z peaks at 710.23 [M+2H]2+, 993.43 [M+5H]5+, 828.03 [M+6H]6+, 1241.28 [M+4H]4+
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.93%
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
99.93% purity by HPLC is excellent and typical for research-grade peptides
Mass spectrometry confirmation
Multiple charge states detected for both BPC-157 and TB-4, with chromatogram showing two distinct peaks consistent with a blend product
Lot number present
Lot 0008 clearly stated
Dates within normal range
Received 2025-11-19, reported 2025-11-21 (2-day turnaround is reasonable)
Lab identification
Freedom Diagnostics with verification URL and contact email provided. Signed by Stephen Schmidt, Principal Chemist
Split report structure
This is a two-page split report: Page 1 covers purity/identity (accession 2511190037), Page 2 covers endotoxin testing (accession 2511190038). Both pages reference the same lot 0008. This split-report format is common practice.
Limited testing scope
Heavy metals, microbial contamination, sterility, and residual solvents/water content not tested. This is common for basic research peptide COAs but limits comprehensive quality assurance.
Professional presentation
Document includes chromatogram, mass spectrum, product photos, appropriate disclaimers, and searchable verification system
