What is BPC-157?
BPC-157, or Body Protection Compound-157, is a synthetic pentadecapeptide consisting of 15 amino acids. It is derived from a protein found in human gastric juice and has been the subject of extensive research since its discovery in the 1990s. The peptide sequence is: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val.
As a stable gastric pentadecapeptide, BPC-157 demonstrates remarkable stability in gastric acid conditions where most peptides would rapidly degrade. This unique property, combined with its research profile, has made it one of the most studied peptides in regenerative research.

Frequently Asked Questions
What makes BPC-157 stable in gastric acid?
BPC-157's unique amino acid sequence and tertiary structure provide resistance to acid hydrolysis. This stability relates to its origin as a fragment of a gastric protein evolved to function in the stomach's harsh environment. Most peptides denature at pH 2-3, while BPC-157 remains active.
How does BPC-157 compare to TB-500 for research?
BPC-157 operates through multiple mechanisms including NO modulation, growth factor upregulation, and FAK-paxillin activation. TB-500 primarily works through actin sequestration and cell migration. BPC-157 shows particular strength in GI and systemic research, while TB-500 excels in muscle/connective tissue models. Many researchers study both.
What is the recommended storage for BPC-157?
Store lyophilized BPC-157 at -20°C for maximum long-term stability. Once reconstituted with bacteriostatic water, refrigerate at 2-8°C and use within 4-6 weeks. BPC-157 has better stability than many peptides but should still follow standard cold storage protocols.
Is BPC-157 approved for human use?
No. BPC-157 is classified as a research peptide and is not approved by the FDA or other regulatory agencies for human use. It is sold strictly for laboratory and research purposes. All published data comes from animal models and in vitro studies.
What concentration should BPC-157 be reconstituted to?
Common research concentrations include 2-2.5mg/ml (2000-2500mcg/ml). For a 5mg vial, adding 2ml of bacteriostatic water yields 2.5mg/ml. Use our peptide calculator to determine the appropriate volume for your desired concentration.
How long does reconstituted BPC-157 remain stable?
Reconstituted BPC-157 stored at 2-8°C typically maintains stability for 4-6 weeks. Some research suggests BPC-157 may have better reconstituted stability than many peptides due to its inherent acid-stability, but standard protocols recommend use within this timeframe.
