What Is BPC-157? A Complete Research Overview
This content is for laboratory research purposes only. Not for human or animal use.
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide — a chain of 15 amino acids — derived from a protein found in gastric juice. Studied in the laboratory for its role in tissue-repair, angiogenesis and wound-healing models, it is notable for its stability. This guide explains what the peptide is, how it works, what it is used for in research, and the purity and storage points that matter when working with it.

What Is BPC-157?
Also known as Body Protection Compound-157, the pentadecapeptide is composed of 15 amino acids — a pentadecapeptide. It corresponds to a partial sequence of a naturally occurring protein identified in gastric juice. A defining practical feature is its robustness: the peptide is notably stable at low pH and resistant to enzymatic breakdown, which is part of why it has become a widely used tool in tissue-repair research in vitro.
That stability, combined with a well-defined 15-residue sequence, gives researchers a reproducible, easy-to-handle compound for probing repair, angiogenesis and inflammatory pathways in controlled experiments.
How It Works
The pentadecapeptide is studied through several proposed mechanisms in laboratory models:
- VEGF modulation: studies suggest it may influence Vascular Endothelial Growth Factor (VEGF) pathways, supporting angiogenesis.
- Growth-factor activation: research indicates it may engage growth factors involved in tissue repair and regeneration.
- Stability at low pH: its resistance to acidic environments makes it a robust, reproducible compound for research.
The value of a defined peptide here is control: adding a known amount to a defined system lets researchers attribute an observed change to the compound rather than to a broader manipulation.
BPC-157 Research Applications
Tissue repair and regeneration
In vitro studies have reported that the peptide may support the repair of various tissues — including muscle, tendon and skin models — in part by promoting the formation of new blood vessels that supply a healing site.
Angiogenesis studies
It has been studied for its potential to stimulate angiogenesis, making it a compound of interest for researchers investigating wound-healing models and vascular repair.
Inflammatory response
Research has also examined the peptide’s potential role in modulating inflammatory pathways, including its influence on the production of cytokines and other inflammatory mediators in model systems.
BPC-157 Purity and Quality
For reproducible results, confirm the identity and purity of the material before use. The specifications below are a useful checklist.
| Property | Specification |
|---|---|
| Appearance | White lyophilised powder |
| HPLC purity | ≥98% (HPLC-verified) |
| Sequence | GEPPPGKPADDAGLV (15 amino acids) |
| Molecular weight | ~1,419.6 g/mol |
| Storage | -20°C, protected from light and moisture |
| COA | Confirms purity, molecular weight and peptide sequence |
Truncated sequences and impurities can confound an assay, so a batch Certificate of Analysis confirming the sequence and HPLC purity is essential. See why peptide purity matters for more on why this underpins reliable research data.
Reconstitution and Handling
The peptide is supplied as a lyophilised powder and is brought into solution before use. For aqueous preparations, bacteriostatic water is commonly used, as its preservative allows a single vial to serve multiple withdrawals under sterile technique. Bring the vial and solvent to room temperature, add the solvent gently down the inside wall, and swirl until fully dissolved. Aliquot the reconstituted solution and store frozen (-80°C for longer-term storage) to minimise freeze-thaw cycles.
BPC-157 vs TB-500: What’s the Difference?
BPC-157 and TB-500 are frequently studied together because their proposed mechanisms are complementary, but they are distinct compounds. See our TB-500 guide for the counterpart overview.
| BPC-157 | TB-500 | |
|---|---|---|
| Research focus | Tissue repair, angiogenesis, inflammatory pathways | Wound healing, cell migration, actin regulation |
| Molecular weight | ~1,419.6 g/mol | ~4,964.4 g/mol |
| Proposed mechanism | VEGF modulation + growth-factor activation | Actin binding + angiogenesis stimulation |
Because the two act through different routes, researchers frequently investigate them side by side in tissue-repair models.
