BPC-157
Synthetic pentadecapeptide derived from a larger Body Protection Compound originally identified in human gastric juice. Studied in preclinical models for tissue repair signalling, angiogenic modulation, and gastrointestinal mucosal integrity.
Mechanism of Action
BPC-157 is a synthetic 15-amino-acid peptide (GEPPPGKPADDAGLV) corresponding to a partial sequence of a larger protein identified in human gastric juice. A notable biochemical property studied in published work is its apparent stability in gastric acid and simulated physiological conditions, which has enabled preclinical investigation of both parenteral and oral administration routes — unusual for a peptide of this length.
The most extensively investigated signalling axis for BPC-157 is angiogenic regulation. Published in vitro and in vivo work has reported upregulation of vascular endothelial growth factor receptor 2 (VEGFR-2) and enhanced endothelial cell migration following exposure. This pathway is believed to contribute to accelerated vascularisation of injured tissue observed in rodent repair models. Additional mechanistic work has described interaction with the nitric oxide (NO) system, including countering NO-synthase inhibition and preservation of vascular tone under pharmacological or surgical stress.
A separate line of investigation has focused on growth hormone receptor expression in tendon fibroblasts. Published data indicate that BPC-157 exposure upregulates growth hormone receptor at the mRNA and protein level, providing a proposed molecular basis for enhanced fibroblast proliferation observed in tendon repair research. Supplementary pathways under study include dopaminergic and serotonergic system modulation, relevant to published observations of broader systemic effects beyond the site of administration.

Researcher FAQ
What is BPC-157?
BPC-157 is a synthetic pentadecapeptide (15 amino acids, sequence GEPPPGKPADDAGLV) derived as a partial fragment of a larger Body Protection Compound originally identified in human gastric juice. In research contexts it is studied for mechanisms related to tissue repair, gastric mucosal integrity, and vascular signalling.
How is BPC-157 typically reconstituted for laboratory use?
BPC-157 is supplied as a lyophilised white powder. Standard research practice is to reconstitute in sterile bacteriostatic water or 0.9% sodium chloride, gently swirling (not shaking) until fully dissolved. Concentration is selected per experimental requirement.
Under what conditions is BPC-157 stable?
Lyophilised BPC-157 is stable at −20 °C for long-term storage. Once reconstituted the peptide is typically stored at 2–8 °C and used within approximately 28 days. Repeated freeze-thaw cycles should be minimised to preserve peptide integrity.
What research category does BPC-157 belong to?
BPC-157 sits within tissue repair research. Published preclinical investigations span musculoskeletal models (tendon, muscle, ligament), gastrointestinal mucosa, and vascular or angiogenic research.
Does BasedPeps provide purity documentation?
Yes. Every BasedPeps lot includes a third-party Certificate of Analysis documenting HPLC purity (≥99%) and mass spectrometric identity confirmation. Certificates of Analysis are available per batch on request.
