Structural Composition
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
Physical Properties
The peptide’s 15-amino-acid configuration contributes to a distinct stability profile. Multiple proline residues within the sequence introduce conformational rigidity, which may enhance resistance to enzymatic degradation. The presence of both acidic residues (glutamic acid and aspartic acid) and a basic residue (lysine) results in a balanced charge distribution, supporting aqueous solubility and potentially influencing molecular interactions under research conditions.

Laboratory Handling and Storage Protocols
Lyophilized Powder Storage
- Store at –20°C to –80°C in the original, sealed vial
- Protect from light exposure and moisture
- A desiccated storage environment is recommended
- Stability data suggests extended stability when stored at −20 °C or below.
Reconstituted Solution Storage
- Short-term storage: Up to 7 days at 4°C
- Long-term storage: Store at –20°C in aliquots
- Use single-use aliquots to preserve peptide integrity
- Minimize freeze–thaw cycles; single-use aliquots are strongly recommended
Stability Characteristics
BPC-157 exhibits a notably robust stability profile relative to many research peptides. Experimental data indicates resistance to degradation across a broad pH range, including acidic environments (pH ~1.5), as well as maintained structural integrity under varied storage conditions. This enhanced stability supports greater flexibility in experimental design and handling protocols.
Frequently Asked Questions
What is BPC-157?
BPC-157 is a synthetic peptide originally derived from a sequence found in gastric proteins. It is commonly used in laboratory and preclinical research to study cellular signaling, tissue response mechanisms, and peptide stability.
Is BPC-157 approved for human use?
No. BPC-157 is not approved by the FDA or any regulatory authority for human consumption or medical treatment. Products sold on this site are strictly for research and laboratory use only.
How is BPC-157 supplied for research purposes?
BPC-157 is typically supplied as a lyophilized (freeze-dried) powder to ensure stability during storage and transport. Researchers reconstitute it according to their experimental protocols using appropriate laboratory techniques.
How should BPC-157 be stored?
Unreconstituted BPC-157 should generally be stored in a cool, dry environment, preferably refrigerated or frozen as specified in the product documentation. Once reconstituted, it should be kept at 2–8°C and used within approximately 30 days.
What quality standards are applied to BPC-157 products?
BPC-157 products are manufactured and handled using research-grade quality standards, including identity verification and purity testing such as HPLC or mass spectrometry, depending on the batch. Certificates of Analysis (COAs) are typically made available for transparency and laboratory reference.
