Pentadecapeptide BPC

Pentadecapeptide BPC (Body Protection Compound) is the core 15-amino acid sequence identified from the larger BPC protein isolated from human gastric juice. This peptide fragment represents the biologically active portion responsible for the gastroprotective and tissue-healing properties observed in studies of the parent protein. It is chemically identical to BPC-157.

The discovery of BPC originated from investigations into the protective factors present in gastric juice that maintain mucosal integrity despite the harsh acidic environment. Researchers identified a protein that demonstrated remarkable cytoprotective properties, and subsequent fractionation revealed that a specific 15-amino acid fragment retained full biological activity.

Pentadecapeptide BPC exhibits extraordinary stability in gastric juice, a property unusual for peptides and essential for its physiological role in gastrointestinal protection. This stability is attributed to its specific amino acid sequence and the absence of sites susceptible to common proteolytic enzymes active in the stomach.

Research has demonstrated pentadecapeptide BPC's effects extend far beyond gastrointestinal protection. The compound influences multiple healing pathways including growth factor expression (particularly EGF and VEGF), nitric oxide synthesis, and GABAergic neurotransmission. These pleiotropic effects have led to investigation in diverse tissue repair contexts including tendon, muscle, bone, and nervous system injury models.
