BPC-157 is a 15-amino-acid synthetic peptide (a pentadecapeptide). TB-500 is a synthetic peptide related to thymosin beta-4. Both are among the most-requested research peptides, and both are short enough that testing should be clean and easy to read. Orion Peptides supplies both as lyophilized compounds for laboratory research only. Not for human or veterinary use.
What “third-party tested” should actually mean
“Third-party tested” only carries weight if three things are true:
- The lab is named. A report from an unnamed lab can’t be checked.
- The method is shown. HPLC gives purity. A separate identity test confirms which peptide it is: mass spectrometry is the strongest, and HPLC against a reference standard is also used. You need both purity and identity.
- The report is batch-specific. It should name a production batch and its test dates.
Accredited labs work to ISO/IEC 17025, the international standard for testing-laboratory competence (ISO). Accreditation isn’t the only marker of a good lab, but it’s worth checking for.
Reading a BPC-157 or TB-500 certificate
| Section | What to look for |
|---|---|
| HPLC | A single dominant peak, purity percentage, chromatogram attached |
| Identity | Mass spec match to the expected mass, or HPLC match to a reference standard |
| Quantity | Measured net peptide content in mg |
| Lab + date | Named lab, batch number and test dates |
Across the market, high purity figures are common, but accurate fill is not. A September 2026 review of 664 vendor certificates found that only 49% of vials were within ±5% of their labelled mass (PepIndex). Always check the quantity line, not just purity. For the full checklist, see our 7-point COA credibility check and How to Read a Peptide COA.

FAQ
Is Orion Peptides BPC-157 third-party tested? Yes. Every batch is tested by a third-party laboratory, and certificates are on the COA Verification page.
Is TB-500 the same as thymosin beta-4? No. TB-500 is a synthetic peptide related to thymosin beta-4, not the full-length protein.
Are these for human use? No. Orion Peptides compounds are for laboratory research only.
