Introduction
BPC-157, or Body Protection Compound-157, is a synthetic pentadecapeptide that has attracted significant attention in the research community. Derived from a partial sequence of a protein found in human gastric juice, BPC-157 has been the subject of numerous preclinical studies investigating its potential biological mechanisms.
In this article, we provide a comprehensive overview of BPC-157 — its structure, mechanism of action, and the current state of published research. All information presented here is intended for educational and research purposes only.
What Is BPC-157?
BPC-157 (also referred to as PL 14736 or Bepecin in some literature) is a pentadecapeptide consisting of 15 amino acids. Its sequence is:
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
It is a partial sequence of the human gastric body protein known as Body Protection Compound, which was first isolated and described in the early 1990s. Unlike many peptides used in research, BPC-157 is noted for its stability in human gastric juice, which is unusual for a peptide of this size.
The molecular formula is C₆₂H₉₈N₁₆O₂₂ with a molecular weight of approximately 1419.53 g/mol. For research applications, BPC-157 is typically supplied as a lyophilized (freeze-dried) powder and reconstituted before use.
Mechanism of Action
The precise mechanism of action of BPC-157 is still under investigation, but published research points to several pathways of interest:
Nitric Oxide (NO) System Several studies suggest that BPC-157 interacts with the nitric oxide system. Research by Sikiric et al. (2014) demonstrated that BPC-157 may modulate both NO synthase and NO release, which plays a role in numerous physiological processes including vascular function and cellular signaling.
Growth Factor Modulation Preclinical studies have observed that BPC-157 may influence the expression of certain growth factors. Research published in the Journal of Physiology has noted upregulation of growth factor receptors in animal models, suggesting a potential role in tissue-related processes.
GABAergic System Research has also explored BPC-157’s interaction with the central nervous system, particularly the GABAergic pathway. Studies in animal models have examined its effects on dopamine and serotonin systems, though this remains an area requiring further investigation.
Angiogenesis Multiple studies have observed that BPC-157 appears to promote the formation of new blood vessels (angiogenesis) in preclinical models. This has been one of the most consistently reported findings across published literature.
Published Research and Studies
BPC-157 has been the subject of over 100 published studies, primarily in animal models. Key areas of investigation include:
Gastrointestinal Research Given its origin from gastric juice protein, much of the early research focused on the gastrointestinal tract. Studies by Sikiric et al. (spanning from the mid-1990s to present) have consistently examined BPC-157’s effects on various GI models in rats, making this the most extensively studied application area.
Musculoskeletal Research Multiple research groups have investigated BPC-157 in preclinical models related to tendons, ligaments, and muscle tissue. Notably, studies by Chang et al. (2011) and Staresinic et al. (2006) examined its effects in rat tendon and muscle models, generating considerable interest in the sports science research community.
Neuroprotection Research More recent studies have explored BPC-157 in neurological contexts. Research published between 2019 and 2023 has examined the peptide in various central nervous system models in rodents, though this remains an emerging area of study.
It is important to note that the vast majority of BPC-157 research has been conducted in vitro (cell cultures) or in animal models. As of the time of writing, no large-scale human clinical trials have been completed and published in peer-reviewed journals.

BPC-157 remains one of the most actively studied peptides in preclinical research, with a growing body of published literature exploring its biological mechanisms. While the absence of large-scale human clinical trials means many questions remain unanswered, the breadth of preclinical data has made it a peptide of significant interest across multiple research disciplines.
