# BPC-157 > Source: https://chooseunscripted.com/peptide/bpc-157/ > Content type: Peptide research profile > Last updated: September 4, 2026 **For research use only. Not for human or veterinary use.** ## Multi-Compound Blend No ## Product URL ## Scientific / Common Name BPC-157 (Body Protection Compound 157) ## Alternative Names / Synonyms Body Protection Compound-157; Bepecin; Gastric Pentadecapeptide; BPC 157; BPC-157 Free Base ## Molecular Formula C₆₂H₉₈N₁₆O₂₂ ## Molecular Weight 1419.5 g/mol ## CAS Number 137525-51-0 ## Clinical Development Phase Phase 1 ## Regulatory Status Investigational; not FDA approved. ## Peptide Classification Synthetic Gastric Pentadecapeptide ## Primary Research Focus Gastrointestinal mucosal integrity; tissue repair; angiogenesis; tendon and ligament healing; musculoskeletal recovery; nitric oxide signaling; inflammatory pathway modulation; vascular response ## Mechanism Summary BPC-157 is a 15-amino-acid peptide derived from a sequence associated with gastric proteins. **Its mechanism of action has not been definitively established**, and much of the proposed mechanistic evidence comes from animal and laboratory studies. Preclinical research suggests BPC-157 may influence **angiogenic signaling, nitric oxide pathways, vascular responses, inflammatory signaling, and extracellular tissue repair**. Studies have also examined interactions with growth-factor-related pathways involved in tendon, ligament, muscle, bone, and gastrointestinal tissue repair. Because no single receptor has been established as the primary pharmacological target of BPC-157, its reported biological effects are better described as **multi-pathway signaling effects** rather than activity at one defined receptor. ## Evidence Summary The evidence base for BPC-157 remains **predominantly preclinical**. A 2025 systematic review of musculoskeletal research identified 36 eligible studies, of which **35 were preclinical and only one was a clinical study**. Animal models have reported effects involving tendon, ligament, muscle, bone, and other tissue-repair processes, but these findings cannot be assumed to establish equivalent effects in humans. Human exposure has occurred, but the clinical evidence is small and limited. FDA’s 2026 review identified small studies involving healthy volunteers and patients with ulcerative colitis, knee pain, and interstitial cystitis, along with two healthy subjects who received intravenous BPC-157. FDA noted that **sample sizes were small, study durations were short, and safety monitoring was limited or unclear in several studies**. A Phase 1 trial was registered to evaluate oral BPC-157 safety and pharmacokinetics in healthy volunteers, but the ClinicalTrials.gov record has not been updated since 2015 and currently carries an unknown status. Overall, controlled human evidence remains insufficient to establish therapeutic efficacy or a well-characterized long-term safety profile. ## Key References - Vasireddi N, et al.

Most published evidence comes from animal or laboratory studies, while available human studies involve small populations and limited follow-up. FDA has specifically noted concerns related to **limited human safety information, possible immunogenicity, peptide aggregation, peptide-related impurities, and challenges in active pharmaceutical ingredient characterization**. These concerns are especially relevant when extrapolating experimental findings to compounded or otherwise unapproved preparations. Reported preclinical findings should therefore not be interpreted as proof of safety or efficacy in humans. Long-term effects, clinically meaningful efficacy, pharmacokinetics across different formulations, and risks associated with different routes of exposure remain incompletely characterized. ## Frequently Asked Questions - ### What is BPC-157? BPC-157 is an investigational 15-amino-acid peptide derived from a sequence associated with gastric proteins. It has been studied primarily in preclinical models involving gastrointestinal integrity, tissue repair, angiogenesis, and musculoskeletal healing. - ### What does BPC-157 target? BPC-157 does not have one established primary receptor. Research has investigated effects involving nitric oxide signaling, angiogenic pathways, vascular responses, growth-factor signaling, and inflammatory pathways. - ### What is BPC-157 being researched for? Research has examined BPC-157 in gastrointestinal, tendon, ligament, muscle, bone, vascular, and wound-repair models. Most of this evidence comes from animal and laboratory studies rather than controlled human trials. - ### Has BPC-157 been studied in humans? Yes. Small human studies and a registered Phase 1 trial have evaluated BPC-157, but the available clinical evidence is limited and does not establish therapeutic efficacy or long-term safety. - ### Is BPC-157 FDA approved? No. BPC-157 is not FDA approved. Its consideration by an FDA advisory committee regarding the 503A Bulks List is a separate compounding-policy process and does not represent drug approval. ## Available Research Compound - [Product page](https://chooseunscripted.com/shop/bpc-157/index.md)
