BPC-157 vs TB-500: What’s the Difference?
BPC-157 and TB-500 are two of the most studied peptides in laboratory research — and the two most commonly researched together. But they are very different molecules with different origins and research profiles. Here’s what sets them apart.

What Is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide — a chain of 15 amino acids — derived from a protein found in human gastric juice. In research settings it is studied primarily for its effects on tissue repair pathways, angiogenesis (formation of new blood vessels), and gastrointestinal research models. It is one of the most widely referenced peptides in the research literature.

What Is TB-500?
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring 43-amino-acid peptide found in virtually all human and animal cells. TB-500 contains the active region of Thymosin Beta-4 (amino acids 17–23). Research focuses on its role in cell migration, actin regulation, and tissue repair models — it is studied in a different mechanistic context than BPC-157.

BPC-157 vs TB-500: Key Differences
| BPC-157 | TB-500 | |
|---|---|---|
| Full name | Body Protection Compound-157 | Thymosin Beta-4 fragment |
| Structure | 15 amino acids (pentadecapeptide) | Fragment of a 43-amino-acid peptide |
| Origin | Derived from a gastric protein sequence | Derived from Thymosin Beta-4 |
| Primary research focus | Tissue repair, angiogenesis, GI models | Cell migration, actin regulation, repair models |
| Typical research vial | 10 mg | 10 mg |
Why Are They Researched Together?
BPC-157 and TB-500 are frequently studied in combination because their research profiles are complementary rather than overlapping — they act through different pathways, which makes the pairing interesting for researchers investigating tissue repair from multiple angles. This combination is popularly known as the “Wolverine Stack.”
For research convenience, the two are also available pre-combined: our Wolverine Stack (TB-500 + BPC-157) supplies both compounds together for laboratory studies.
Which One for Your Research?
- Studying gastric or angiogenesis pathways? BPC-157 is the more referenced compound in that literature.
- Studying cell migration or actin dynamics? TB-500’s Thymosin Beta-4 lineage makes it the relevant choice.
- Investigating repair pathways broadly? Researchers often study both — separately or as a stack — to compare and contrast effects.
As with any research chemical, the right choice depends entirely on your protocol and research question.
Quality Matters for Both
Because BPC-157 and TB-500 are among the most in-demand research peptides, they are also among the most counterfeited. Insist on third-party tested product with an available Certificate of Analysis — every BioMatrix batch is tested, and COAs are available on request.
