What is BPC-157?

BPC-157 (Body Protection Compound-157) is a 15-amino acid peptide derived from a partial sequence of human gastric juice protein. Its mechanism of action involves upregulation of growth factor expression including VEGF (vascular endothelial growth factor), FGF (fibroblast growth factor), and activation of the FAK-paxillin signaling pathway, which collectively promote angiogenesis, fibroblast migration, and collagen deposition. Extensive preclinical research from the laboratory of Predrag Sikiric at the University of Zagreb has demonstrated BPC-157's effects across numerous animal models including tendon transection (Staresinic et al., Journal of Orthopaedic Research, 2003), muscle crushing injuries, ligament healing, and gastrointestinal lesion repair. Studies suggest BPC-157 operates through the nitric oxide (NO) system and interacts with the dopaminergic system, which may explain its observed gastroprotective and cytoprotective properties in rodent models. Compared to other tissue repair peptides like TB-500 (Thymosin Beta-4), BPC-157 appears to have a stronger affinity for gastrointestinal tissue repair and tendon healing, while TB-500 shows broader systemic tissue migration. BPC-157 is notably stable in human gastric juice, an unusual property for a peptide. Most published research remains in animal models; no large-scale human clinical trials have been completed to date. Store lyophilized powder at -20C; reconstitute with bacteriostatic water and refrigerate at 2-8C for up to 14 days. BPC-157 is among the most widely studied peptides in regenerative medicine laboratories, orthopedic research institutions, and gastroenterology departments.

BPC-157 Research Applications

In published and preclinical research, BPC-157 has been studied across the following areas:

  • Wound healing and tissue regeneration
  • Angiogenesis and vascular repair
  • Tendon, ligament, and connective tissue support
  • Gastrointestinal health studies

BPC-157 in Research: Reconstitution & Study Concentrations

BPC-157 is a stable gastric pentadecapeptide investigated in preclinical models of tendon, ligament, muscle and gut-mucosal repair (Sikiric et al.). Published animal research uses concentrations expressed per kilogram of body weight in the model organism — these are not human doses. For in-vitro work the lyophilized peptide is reconstituted with bacteriostatic water to a defined mg/mL concentration. BPC-157 is not FDA-approved and is supplied for research use only.

Worked example: a 5mg vial reconstituted with 2 mL of bacteriostatic water yields 2.50 mg/mL.

BPC-157 — Frequently Asked Questions

What is BPC-157 and how does it work?
BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a partial sequence of human gastric juice protein. It consists of 15 amino acids and has been observed in preclinical models to promote angiogenesis (new blood vessel formation), upregulate growth factor expression (including VEGF, EGF, and FGF), and modulate the nitric oxide (NO) system. These mechanisms contribute to its studied effects on tissue repair and cytoprotection.
What research has been done on BPC-157?
Over 100 published studies have examined BPC-157 in various animal models. Research published in the Journal of Physiology-Paris demonstrated accelerated tendon-to-bone healing in rat models. Studies in Current Pharmaceutical Design showed gastric ulcer protection and intestinal anastomosis healing. Additional preclinical work has explored nerve regeneration (crushed sciatic nerve models), muscle healing, and corneal injury repair.
How does BPC-157 compare to TB-500 (Thymosin Beta-4)?
Both BPC-157 and TB-500 are studied for tissue repair, but they work through different mechanisms. BPC-157 primarily acts through NO system modulation and growth factor upregulation, with strong gastrointestinal cytoprotective effects. TB-500 promotes tissue repair through actin sequestration and cell migration. Many researchers study them in combination (the Wolverine stack) for potential synergistic effects across different repair pathways.
What is the recommended reconstitution protocol for BPC-157?
For this 5mg vial, add 1 mL of bacteriostatic water to yield a concentration of 5.0mg/mL. Draw 10 units on a 1mL insulin syringe for a 500 mcg dose. Inject BAC water slowly along the inner vial wall — do not shake. Allow the powder to dissolve fully (2–5 minutes). Administer AM and PM, every day. Refrigerate reconstituted solution at 2–8°C and use within 30 days.
Is BPC-157 the same as TB-500?
No. BPC-157 is a 15-amino-acid gastric peptide; TB-500 is a fragment of thymosin beta-4. Both are studied in tissue-repair research and are sometimes combined in research blends, but they are distinct molecules with different mechanisms.
Is BPC-157 legal to buy for research?
BPC-157 is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.
How is BPC-157 reconstituted for research use?
BPC-157 ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.
Does BPC-157 come with a Certificate of Analysis?
Yes. Every batch of BPC-157 from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
