What is BPC-157? A Complete Guide
BPC-157 is a synthetic peptide derived from a protective protein in the human stomach. Here's everything you need to know about this remarkable research compound.
Definition and Origin
BPC-157 stands for Body Protection Compound-157. It is a pentadecapeptide — a chain of exactly 15 amino acids — that was isolated and studied starting in the 1990s by researchers including Dr. Predrag Sikirić and his team at the University of Zagreb in Croatia.
The compound is derived from a naturally occurring protein found in human gastric juice (stomach secretions). This protein was discovered to have remarkable cytoprotective (cell-protecting) properties, and BPC-157 was synthesized to study and replicate these effects.
Amino Acid Sequence
The full amino acid sequence of BPC-157 is: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
It has the molecular formula C62H98N16O22 and a molecular weight of approximately 1419.6 g/mol. The compound is also known as PL 14736 in some research literature.
How BPC-157 Works
BPC-157 exerts its effects through multiple mechanisms:
- Angiogenesis promotion — stimulates formation of new blood vessels, improving blood flow to injured tissue
- Growth factor upregulation — increases expression of VEGF (vascular endothelial growth factor) and other healing factors
- Nitric oxide system modulation — affects the NO-system which controls vascular tone and inflammation
- Collagen synthesis — promotes production of collagen in tendons and connective tissue
- Neurotransmitter interaction — modulates dopamine and serotonin systems in the central nervous system
- Anti-inflammatory effects — reduces NF-κB inflammatory pathway activity
Why BPC-157 is Unique Among Peptides
Most therapeutic peptides are rapidly degraded by stomach acid when taken orally, which is why they typically require injection. BPC-157 is remarkable because it is stable in gastric juice — the same environment from which it was originally isolated. This means it retains activity when taken orally, though injectable forms still show superior bioavailability for localized injury treatment.
Research History
BPC-157 has been studied extensively in animal models over 30+ years. Research has demonstrated efficacy in:
- Tendon and ligament healing (multiple studies, 1993–2024)
- Gastrointestinal protection and healing
- Muscle injury repair
- Bone healing and fracture recovery
- Neuroprotection and neurological conditions
- Cardiovascular protection
As of 2026, BPC-157 has entered Phase II clinical trials in humans for inflammatory bowel disease (IBD) treatment, making it one of the more clinically advanced research peptides.
Current Status
BPC-157 is classified as a research chemical in most countries. It is not an FDA-approved drug, though the underlying research is quite advanced. It is sold by peptide vendors for research purposes and is widely used by athletes, biohackers, and individuals seeking healing support — though this represents off-label use.
