BPC-157 (10mg)

BPC-157 Research Background

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide: a stable, partial sequence corresponding to a fragment of a protein identified in gastric juice. Its 15-residue chain (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) is not found intact in nature, and it is produced synthetically for laboratory work. Within the research literature the compound is often described as a "stable gastric pentadecapeptide," a label that reflects its notable resistance to hydrolysis in aqueous and enzymatic conditions relative to many short peptides. This characterization has made it a frequently cited model compound in mechanistic and gastrointestinal studies.

Interest in BPC-157 as a research material centers on how a small, sequence-defined peptide behaves across a range of in-vitro and preclinical systems. It is used as a reference peptide in assays exploring cellular signaling, angiogenesis-related pathways, and tissue-culture responses. The peptide has no established consumer application, and the body of work surrounding it remains preliminary and ongoing; findings from cell-based and rodent-model studies should not be extrapolated to human or animal outcomes.

What Has Been Studied in Preclinical Models

Published investigations of BPC-157 are predominantly rodent-model and in-vitro in nature. Reported experimental lines of inquiry include interactions with nitric oxide (NO) system pathways, effects observed in cell-migration and wound-closure scratch assays, and studies examining vascular and connective-tissue endpoints in controlled preclinical settings. Researchers have also used it to probe growth-factor receptor expression, such as VEGFR2 signaling, in cultured endothelial cells.

• Cell-culture models examining fibroblast migration and tubule formation.
• Rodent-model studies of connective-tissue and gastrointestinal endpoints.
• Mechanistic work on nitric-oxide-related signaling pathways.
• Stability and receptor-interaction assays used to characterize peptide behavior in vitro.

These references describe experimental laboratory work only. They are not medical claims, are not evidence of safety or efficacy in humans or animals, and should not be interpreted as guidance for any use outside a controlled research environment.

Analytical Characterization

Each research lot is supplied as a lyophilized white powder and characterized before release. Identity and purity are established using orthogonal analytical methods so that the material on the Certificate of Analysis (COA) matches the sequence and mass expected for the pentadecapeptide. This dual-method approach separates purity (how much of the sample is the target peptide) from identity (confirmation that the target is the correct molecule).

• HPLC (RP-HPLC) purity: quantified by peak-area integration, with lot purity reported on the COA (typically ≥98–99%). The chromatogram resolves the main peak from process-related impurities and truncated sequences.
• Mass-spectrometry identity: ESI-MS or MALDI-TOF confirms the observed monoisotopic/average mass against the theoretical value for the sequence, verifying molecular identity.
• Supporting data: appearance, net peptide content, and residual-solvent or water-content checks where applicable.

The COA accompanying each product is the definitive analytical record for that specific lot. Because purity and mass can vary slightly between synthesis batches, researchers should reference the COA tied to the lot number received rather than generic specifications when documenting experimental inputs. Retaining the COA alongside experimental records supports reproducibility and traceability.

Laboratory Handling of Lyophilized Material

As a lyophilized peptide, BPC-157 is hygroscopic and sensitive to repeated temperature cycling. Standard laboratory practice is to allow sealed vials to equilibrate to room temperature before opening to minimize condensation, and to reconstitute with an appropriate research-grade solvent under aseptic technique. Aliquoting reconstituted stock into single-use portions limits freeze-thaw cycles that can degrade peptide integrity. Detailed temperature and stability windows for lyophilized, reconstituted, and working solutions appear in the storage table on this page.
