Description
BPC-157 Peptide Overview
BPC-157 Peptide is a synthetic 15-amino-acid peptide that has been investigated in preclinical research involving peptide biology, cellular signaling, gastrointestinal biology, vascular processes, and tissue-related research.
BPC-157 is commonly identified as a peptide fragment with the sequence GEPPPGKPADDAGLV. PubChem lists the free peptide with molecular formula C₆₂H₉₈N₁₆O₂₂, molecular weight approximately 1419.5 g/mol, and CAS number 137525-51-0.
Because BPC-157 may be supplied in different chemical forms, such as free peptide or salt forms, researchers should verify the exact form supplied. For example, PubChem separately identifies BPC-157 acetate and BPC-157 TFA salt, which have different molecular formulas and molecular weights.
Research Use Only: BPC-157 Peptide is supplied for laboratory and scientific research purposes only. It is not intended for human or veterinary use, diagnosis, treatment, cure, or prevention of disease.
What Is BPC-157 Peptide?
BPC-157 is a synthetic 15-amino-acid peptide that has been investigated primarily in preclinical laboratory research.
Its sequence is:
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
or, using the one-letter amino-acid code:
GEPPPGKPADDAGLV.
Research involving BPC-157 has explored several biological pathways and experimental models. However, findings from preclinical research should not automatically be interpreted as evidence of established therapeutic effects in humans.
For laboratory researchers, BPC-157 may be relevant to studies involving:
- Synthetic peptide characterization
- Peptide chemistry
- Cell-signaling research
- Gastrointestinal biology
- Vascular and cellular research
- Peptide structure–activity relationships
- Preclinical biological studies
The exact chemical form is particularly important when comparing BPC-157 products because free peptide and salt forms have different molecular weights.
Molecular Formula, Molecular Weight & Sequence
For the free BPC-157 peptide, commonly reported specifications include:
| Property | Specification |
|---|---|
| Product name | BPC-157 Peptide |
| Peptide type | Synthetic pentadecapeptide |
| Length | 15 amino acids |
| Sequence | GEPPPGKPADDAGLV |
| Full sequence | H-Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val-OH |

These specifications correspond to the free BPC-157 compound listed by PubChem.
Important chemical-form note
Researchers should not assume that every product labeled “BPC-157” has the same molecular weight.
For example, PubChem lists:
- BPC-157 free peptide: approximately 1419.5 g/mol
- BPC-157 acetate: approximately 1479.6 g/mol
- BPC-157 TFA salt: approximately 1647.6 g/mol
These differences result from the associated counterions and are important when interpreting mass-spectrometry results and calculating peptide quantities.
For this reason, a professional product page should identify the exact chemical form supplied.
Purity
A typical research-grade specification for BPC-157 Peptide may be:
Purity: ≥98% by HPLC
The actual purity should always be confirmed using the batch-specific Certificate of Analysis (COA).
Depending on the testing package, documentation may include:
- HPLC purity percentage
- HPLC chromatogram
- Mass spectrometry
- Calculated molecular weight
- Observed molecular weight
- Lot or batch number
- Testing date
- Net peptide quantity
A professional research supplier should connect the analytical results to the exact lot number supplied to the researcher.
Important: If your product is a specific BPC-157 salt, such as acetate or TFA, the COA and product specification should identify that form clearly.
Appearance
Appearance: White to off-white lyophilized powder.
BPC-157 may be supplied as a lyophilized powder for controlled laboratory storage and handling.
The exact appearance can vary slightly depending on formulation, drying conditions, packaging, and batch characteristics.
Visual appearance alone cannot establish peptide identity or purity. Researchers should rely on appropriate analytical testing, particularly HPLC and mass spectrometry, when identity or purity needs to be verified.
5. Available Vial Sizes
BPC-157 Peptide can be offered in several research quantities depending on laboratory requirements and available inventory.
Common vial sizes include:
- 2 mg
- 5 mg
- 10 mg
- 20 mg
- 50 mg
For many laboratory projects, 5 mg and 10 mg formats are practical research quantities.
Larger quantities may be suitable for laboratories performing repeated analytical work or multiple research projects.
Always state the net peptide quantity clearly on the product page and vial label.
Storage Recommendations
Proper storage helps protect the quality of lyophilized peptide material.
For lyophilized BPC-157:
- Follow the storage temperature specified in the product documentation.
- Keep the vial tightly sealed when not in use.
- Protect the material from excessive moisture.
- Minimize exposure to heat and direct light.
- Avoid unnecessary temperature cycling.
- Allow a cold vial to equilibrate appropriately before opening to minimize condensation.
Controlled frozen storage may be appropriate for long-term storage when supported by the applicable stability information.
Important: Storage conditions can vary according to the specific formulation and batch. The storage instructions supplied with the product should take priority.
Reconstitution Information
BPC-157 Peptide is supplied as a lyophilized research material. When reconstitution is required for a laboratory experiment, researchers should select a compatible solvent and concentration based on their validated research protocol.
General laboratory considerations include:
- Allow the sealed vial to reach an appropriate temperature before opening.
- Use a compatible laboratory-grade solvent.
- Introduce the solvent carefully.
- Avoid unnecessarily vigorous agitation.
- Allow sufficient time for the material to dissolve.
- Minimize excessive foaming.
- Consider aliquoting when appropriate to reduce repeated freeze–thaw exposure.
- Record the solvent, concentration, preparation date, and storage conditions.
There is no universal reconstitution volume appropriate for every BPC-157 research application.
Researchers should determine the concentration required for their experiment and calculate the appropriate solvent volume accordingly.
