BPC-157 is a 15-residue gastric-derived sequence (GEPPPGKPADDAGLV) listed as a lyophilized research compound. Popular write-ups skip the lot paper. This overview is identity and published lab context โ not a repair protocol.
Chemical Identity
BPC-157 has the amino acid sequence H-Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val-OH. It is a fragment of the larger BPC protein identified in gastric juice research. The peptide has a molecular weight of approximately 1,419.5 Da.
Research Applications
In published preclinical research, BPC-157 has been studied in several contexts:
- cell-migration models: Studies have examined BPC-157 in tendon, ligament, and muscle tissue cultures to evaluate cellular proliferation and migration responses.
- Gastrointestinal research: As a gastric-derived peptide, BPC-157 has been investigated for its effects on intestinal epithelial cell behavior in vitro.
- Angiogenesis studies: Research has explored BPC-157's influence on vascular endothelial growth factor (VEGF) signaling pathways in controlled laboratory settings.
- Anti-inflammatory signaling: Several in vitro studies have examined BPC-157's interaction with inflammatory cytokine pathways.
Evaluating BPC-157 Lot Quality
When sourcing BPC-157 for laboratory research, lot documentation is the primary indicator of reagent quality. A Certificate of Analysis (COA) should include:
- HPLC purity analysis โ confirming peptide purity percentage at a specified wavelength
- Mass spectrometry (MS) data โ confirming molecular weight and identity
- Lot number and manufacture date โ for traceability
- Laboratory name and testing method โ the testing facility should be identified
Requesting a COA before you inquire is standard practice in reagent sourcing. BioLabs Research provides lot docs on request when available. See our guide to reading a COA for a detailed breakdown of what each section means.
BPC-157 vs. TB-500: Research Context
BPC-157 and TB-500 (a fragment of Thymosin Beta-4) are often studied together in cellular signaling research. While BPC-157 is a gastric-derived peptide, TB-500 is a thymus-derived peptide fragment. Both have been examined in cell-migration models, but through different proposed signaling pathways. Some researchers source both as a blend for comparative studies. See our BPC-157 / TB-500 Blend listing.
Sourcing BPC-157 for Research
When selecting a BPC-157 supplier for laboratory use, prioritize:
- Lot docs on request โ read the issuing laboratory name and lot ID on the file when one is issued
- Lot traceability โ each lot should have a unique identifier and test documentation
- Purity specifications โ HPLC purity as reported on the lot docs
- Transparent pricing โ research reagents should have clear, published pricing
Keep each figure tied to a distinct receiving check: label identity, lot paper, and โ when applicable โ pack presentation. Adjacent screenshots without intervening notes make audits harder to reconstruct.
