What is BPC-157?
BPC-157 (Body Protection Compound 157) is a synthetic peptide made of 15 amino acids. Its sequence is a partial fragment of a larger protein originally identified in human gastric juice. The material itself is produced by solid-phase peptide synthesis and supplied as a lyophilised powder.
BPC-157 is classified as a research chemical and is supplied strictly for in-vitro laboratory research.
Chemistry and structure
BPC-157 is a linear pentadecapeptide with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val (GEPPPGKPADDAGLV), CAS registry number 137525-51-0, molecular formula C62H98N16O22 and a monoisotopic mass of approximately 1419.6 g/mol for the free acid. Commercial material is commonly supplied as an acetate salt; the certificate of analysis for each batch records the form tested.
BPC-157 in the research literature
BPC-157 appears widely in the laboratory literature, primarily in in-vitro and cell-culture studies. Index Peptides lists it as a technical research material only and takes no position on any application.
Researchers comparing published work should note that methods and materials vary substantially between papers, which is one reason batch-level identity and purity documentation matters for reproducibility.
Supply status
Index Peptides supplies BPC-157 strictly as a research chemical for in-vitro laboratory research. Products are sold exclusively to qualified researchers and licensed laboratories. It is not for human or veterinary use.
Form, handling and storage
BPC-157 is supplied as a lyophilised (freeze-dried) powder in a sealed vial. Lyophilised peptides are best stored at -20°C, desiccated and protected from light; long-term stability data are batch-specific and recorded against the batch record. Handling is the responsibility of the qualified researcher.

Frequently asked questions
Who is BPC-157 supplied to?
Index Peptides supplies BPC-157 exclusively to qualified researchers and licensed laboratories, for in-vitro research only. It is not for human or veterinary use.
What formats does Index Peptides supply?
BPC-157 is listed as 5mg and 10mg single-compound vials, and as part of multi-peptide blend vials. Every format carries the same batch documentation requirements.
How is each batch verified?
By reversed-phase HPLC for purity and LC-MS for identity (expected vs detected mass). The certificate of analysis is published on the product page, and any batch can be checked by its lot number on the verify page.
How should BPC-157 be stored?
As supplied (lyophilised), store at -20°C, desiccated and protected from light, per the batch record.
What is the shelf life of BPC-157?
As supplied (lyophilised powder in a sealed vial), BPC-157 is stored at -20C, desiccated and protected from light. Long-term stability is documented per batch on the certificate of analysis; treat the batch record as the authoritative shelf-life reference for that lot.
What is the difference between the sizes?
The difference is the nominal peptide content per vial. BPC-157 is supplied as 5mg and 10mg single-compound vials, plus blend vials. Every format carries the same batch documentation and purity testing.
What does the certificate of analysis show?
Review the published certificate for the exact lot, including the laboratory, report date and analytical results actually reported. HPLC purity alone does not confirm LC-MS identity. Contact us before ordering if a required result is not published.
