A Systematic Review of BPC-157: Efficacy, Mechanisms, and Safety
Dr. Thanawat Chen
Abstract
This systematic review evaluates the efficacy, mechanisms of action, and safety profile of Body Protection Compound-157 (BPC-157), a synthetic pentadecapeptide derived from human gastric juice. Analyzing 54 preclinical studies and limited human data from 2000-2025, BPC-157 demonstrates promise in tissue repair, inflammation modulation, and neuroprotection, primarily in rodent models (n=1,200+ subjects). However, the absence of large-scale human trials limits clinical applicability. Key findings include accelerated healing of musculoskeletal and gastrointestinal tissues, with minimal reported toxicity. Safety concerns persist due to unregulated use and insufficient pharmacokinetic data in humans.
Introduction
BPC-157, a 15-amino-acid peptide (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val), has garnered attention for its regenerative potential. Initially identified in gastric juice, it exhibits stability against enzymatic degradation, suggesting therapeutic promise. Preclinical studies highlight its role in healing tendons, muscles, and the gut, yet its translation to human use remains unapproved by regulatory bodies like the FDA. This review aims to synthesize evidence on BPC-157’s efficacy and safety, addressing gaps in human research.
Key Research Questions:
- What are the primary therapeutic effects of BPC-157?
- Which mechanisms underpin its regenerative properties?
- What is the safety profile across species?

Discussion
BPC-157 enhances angiogenesis, collagen synthesis, and growth factor expression (e.g., VEGF), driving tissue repair in preclinical models. Neuroprotective effects in CNS injury models suggest broader applications. However, human evidence is anecdotal or limited to small cohorts (e.g., one 12-patient knee study). Safety data show no significant toxicity in animals, but human pharmacokinetics remain unclear, raising concerns about unregulated use.
Strengths
- Consistent preclinical efficacy
- Broad tissue applicability
Limitations
- Lack of RCTs in humans
- Potential bias in study origins
Conclusion
BPC-157 shows significant regenerative potential in preclinical settings, but its clinical utility is hindered by insufficient human data. Rigorous trials are needed to validate efficacy and establish safety, particularly given its current unregulated status.
