BPC-157
Body Protection Compound-157 — a synthetic pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. The most widely studied regenerative peptide, with extensive animal research demonstrating healing effects on tendons, ligaments, muscles, the gut, and multiple organ systems. Uniquely stable in gastric acid, enabling both injectable and oral administration.
Typical Dosage
Standard: 200-800 mcg subcutaneous once daily, or 500-1000 mcg oral once daily. Often cycled 4-6 weeks on, 2 weeks off. Injectable may be administered near the injury site for localized healing. Oral route used primarily for gut-related conditions.
Administration
Subcutaneous injection, intramuscular injection, or oral
Mechanism of Action
BPC-157 is a synthetic pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. Its mechanism of action is remarkably multifaceted, affecting multiple organ systems and healing pathways simultaneously, which is unusual for a single peptide. The primary mechanism centers on the nitric oxide (NO) system — BPC-157 modulates both constitutive (eNOS) and inducible (iNOS) nitric oxide synthase, and can either promote or inhibit NO production depending on the tissue context and injury state.
BPC-157's regenerative effects are mediated through upregulation of multiple growth factors. It increases expression of vascular endothelial growth factor (VEGF), promoting angiogenesis — the formation of new blood vessels at injury sites, which is critical for delivering oxygen and nutrients for tissue repair. It also upregulates epidermal growth factor (EGF), nerve growth factor (NGF), and hepatocyte growth factor (HGF) receptors, supporting wound healing, nerve regeneration, and organ protection respectively. In tendon and ligament injuries, BPC-157 stimulates fibroblast migration and proliferation, accelerating collagen deposition and organized tissue repair rather than scar formation.
Beyond structural healing, BPC-157 has significant effects on the central and enteric nervous systems. It modulates dopaminergic, serotonergic, GABAergic, and opioid systems, which may explain reported effects on mood, gut function, and pain perception. It protects endothelial function, counteracts the effects of NSAIDs on the gastric mucosa, and has demonstrated cytoprotective effects in models of liver, brain, heart, and intestinal damage. The peptide also interacts with the FAK-paxillin pathway, which is central to cell adhesion and migration during wound healing. Its stability in gastric juice — unusual for a peptide — enables oral administration, making it one of the few peptides effective by both injectable and oral routes.

Abstract
Background: No Fourier transform infrared (FTIR) spectroscopy studies have directly evaluated adrenalectomy vessels, the technique's established ability to probe collagen/elastin-associated spectral features and lipid peroxidation-related signatures, and protein structural damage. Stable gastric pentadecapeptide BPC 157 therapy was found to maintain the vascular function under severe stress, as FTIR spectroscopy recently demonstrated rapid peptide-induced molecular changes in healthy rat blood vessels, particularly in lipid content and protein secondary structure. Methods: To extend these findings and highlight the BPC 157 vascular background in the special circumstances of the course following unilateral adrenalectomy, abdominal aortas were collected at 15 min, 5 h, and 24 h after unilateral adrenalectomy for the FTIR spectroscopy assessment. Results: FTIR spectra were acquired, preprocessed, and analyzed using principal component analysis (PCA), support vector machine discriminant analysis (SVMDA), and band-specific statistics. BPC 157 (10 ng/kg intragatrically immediately after unilateral adrenalectomy) produced a clear, reproducible separation of aortic spectra from control samples at all time points. The main discriminatory spectral signatures were observed in three regions, including amide I and amide II (protein-related bands, consistent with collagen/elastin contributions) and lipid C-H stretching bands. These spectral signatures are consistent with early extracellular matrix reinforcement and membrane preservation in the vascular wall and align with the recovering effect on the lesions in counteraction of the severe vascular and multiorgan failure, attenuation/elimination of thrombosis and blood pressure disturbances in various occlusion/occlusion-like syndromes. Conclusions: Together, after unilateral adrenalectomy, the FTIR data provide molecular-level spectral signatures consistent with rapid remodeling of the aortic wall toward a more structurally stable and functionally favorable state.

Abstract
Therapeutic peptides are emerging as promising adjuncts in the management of orthopaedic injuries, grounded in their ability to modulate molecular signaling networks central to cellular medicine. By acting on key pathways such as PI3K/Akt, mTOR, MAPK, TGF-β, and AMPK, peptides exert influence over tissue regeneration, inflammation resolution, and neuromuscular recovery. Wound-healing peptides such as BPC-157, TB-500, and GHK-Cu promote angiogenesis, integrin-mediated extracellular matrix remodeling, and fibroblast activation, whereas growth hormone secretagogues like ipamorelin, CJC-1295, tesamorelin, sermorelin, and AOD-9604 activate IGF-1 signaling and satellite cell repair. Recovery-enhancing agents such as epithalon, delta sleep-inducing peptide, and pinealon target circadian and mitochondrial regulators, and neuroactive peptides like selank, semax, and dihexa enhance brain-derived neurotrophic factor and HGF/c-Met pathways critical to neuroplasticity. Although preclinical studies are promising, there is a current lack of clinical trials. This review integrates current mechanistic insights with orthopaedic relevance, emphasizing safety, efficacy, and future directions for responsible integration into musculoskeletal care.

Abstract
Therapeutic peptides are short-chain amino acids that regulate cellular functions and facilitate biochemical processes. In recent years, there has been significant growth in the global market for therapeutic peptides and thus its popularity among patients. Given the increase in the development of peptides and increased marketing to patients for orthopaedic injuries, it is critical for orthopaedic surgeons to understand the current evidence behind these therapeutic peptides.

Abstract
The healing issue is a central, not completely understood, problem in pharmacology, approached by many concepts. One of the most well-known is Robert's and Szabo's concept of cytoprotection, which holds innate cell (epithelial (Robert), endothelial (Szabo)) integrity, protection/maintenance/reestablishing in the stomach to be translated to other organ therapy (cytoprotection→organoprotection) via cytoprotection agent's effect. Thereby, we defend stable gastric pentadecapeptide BPC 157 therapy, efficacy, pleiotropic beneficial effects along with high safety (LD1 not achieved) against Józwiak and collaborators' review speculating its negative impact, speculation of angiogenesis toward tumorogenesis, increased NO and eNOS, toward damaging free radicals formation, and neurodegenerative diseases (Parkinson's disease and Alzheimer's disease). Contrarily, in wound healing and general healing capabilities as reviewed, as a cytoprotective agent, and native cytoprotection mediator, BPC 157 controls angiogenesis and the NO-system healing functions, and counteracts the pathological presentation of neurodegenerative diseases in acknowledged animal models (i.e., Parkinson's disease and Alzheimer's disease), and presents prominent anti-tumor potential, in vivo and in vitro. BPC 157 resolved cornea transparency maintenance, cornea healing "angiogenic privilege" (vs. angiogenesis/neovascularization/tumorogenesis), does not produce corneal neovascularization, but rather opposes it, and per Folkman's concept, it demonstrates anti-tumor effect in vivo and in vitro. BPC 157 exhibits a distinctive effect on NO-level (increase vs. decrease), always combined with counteraction of free radicals formation, and in mice and rats, BPC 157 therapy counteracts Parkinson's disease-like and Alzheimer's disease-like disturbances. Thus, BPC 157 therapy means targeting angiogenesis and NO's cytotoxic and damaging actions, but maintaining, promoting, or recovering their essential protective functions.

Abstract
Background: Body protection compound-157 (BPC-157) is a naturally occurring gastric peptide that promotes mucosal integrity and homeostasis. Preclinical studies show its potential for promoting healing in musculoskeletal injuries such as fractures, tendon ruptures, ligament tears, and muscle injuries. Despite lacking US Food and Drug Administration approval and its use being banned in professional sports, it is increasingly used by clinicians and athletes. Purpose: We sought to (1) provide a comprehensive synthesis of the BPC-157 literature from an orthopedic sports medicine perspective and (2) elucidate the mechanism of action, musculoskeletal effects, metabolism, and safety profile. Methods. We conducted a systematic review of English-language literature, published from database inception to June 3, 2024, from PubMed, Cochrane, and Embase. We searched PROSPERO to identify any current or unpublished reviews. Studies reporting BPC-157's mechanism, musculoskeletal outcomes, metabolism, and safety were included. Articles were screened in 3 phases by 2 reviewers. In cases of a disagreement between the 2 reviewers, blinding was removed, and eligibility was determined by group consensus, with a third author making the final decision. Results. A total of 544 articles from 1993 to 2024 were identified. After duplicates were removed, 36 studies were included (35 preclinical studies, 1 clinical study). The studies suggest that BPC-157 enhances growth hormone receptor expression and several pathways involved in cell growth and angiogenesis, while reducing inflammatory cytokines. In preclinical models, BPC-157 improved functional, structural, and biomechanical outcomes in muscle, tendon, ligament, and bony injuries. In a retrospective study of musculoskeletal pain following intraarticular injection of BPC-157 for unspecified chronic knee pain, 7 of 12 patients reported relief for >6 months. BPC-157 is metabolized in the liver, with a half-life of less than 30 minutes, and is cleared by the kidneys. Preclinical safety studies showed no adverse effects across several organ systems. No clinical safety data were found. Conclusion: This systematic review of level IV and level V studies suggests that BPC-157 shows promise for promoting recovery from musculoskeletal injuries. Adverse effects are possible due to unregulated manufacturing, contamination, or unknown clinical safety. We recommend that clinicians counsel athletes to understand their organizations' rules to remain compliant with medication/supplement safety and testing standards.

Abstract
BPC 157, known as the "Body Protection Compound", is a pentadecapeptide isolated from human gastric juice that demonstrated its pleiotropic beneficial effects in various preclinical models mimicking medical conditions, such as tissue injury, inflammatory bowel disease, or even CNS disorders. Unlike many other drugs, BPC 157 has a desirable safety profile, since only a few side effects have been reported following its administration. Nevertheless, this compound was temporarily banned by the World Anti-Doping Agency (WADA) in 2022 (it is not currently listed as banned by the WADA). However, it has not been approved for use in standard medicine by the FDA and other global regulatory authorities due to the absence of sufficient and comprehensive clinical studies confirming its health benefits in humans. In this review, we summarize information on the biological activities of BPC 157, with particular reference to its mechanism of action and probable toxicity. This generated the attention of experts, as BPC 157 has been offered for sale on many websites. We also present recent interest in BPC 157 as reflected in a number of patent applications and granted patents.
