Description
Structure & Identity
This is a two-peptide blend. BPC-157 (arginine salt) is the 15-amino-acid body-protection-compound peptide prepared as its arginine salt (CAS of the free peptide 137525-51-0). KPV is the tripeptide Lys-Pro-Val, the C-terminal fragment of alpha-MSH (CAS 67727-97-3). The two are combined in equal 500 mcg amounts, each retaining its own structure and receptor targets.
Research Background
The pairing joins a repair-signaling peptide with a melanocortin-pathway one.
- BPC-157 signaling. BPC-157 is studied in angiogenesis and cytoprotection models. [PMID: 30915550].
- BPC-157 angiogenesis. Its angiogenesis and nitric-oxide signaling is an active area [PMID: 41155565].
- KPV signaling. KPV is the alpha-MSH C-terminal fragment studied for NF-kB-pathway signaling [PMID: 12750433].
- KPV epithelial models. It has been studied in murine gut-epithelial signaling research [PMID: 18092346].
- Combined rationale. Bringing repair-signaling and melanocortin-pathway signaling into one preparation supports parallel study.
These are research contexts, not approved uses, and the blend is intended for laboratory study.

Storage & Handling
Store the sealed vial frozen at -20°C, shielded from light, until use. After reconstitution, keep the solution refrigerated at 2-8°C and use it within about two weeks. Let the vial reach room temperature before opening, and avoid repeated freeze-thaw cycles to protect both peptides.
Quality Assurance
The components are produced under research-grade manufacturing controls and verified by an independent lab before release. Purity is measured by reverse-phase HPLC and identity by mass spectrometry, with that testing done by third-party laboratories such as Janoshik Analytical along with domestic US labs. A certificate of analysis accompanies each batch, tying the results to your material.
Frequently Asked Questions
What is this BPC-157 / KPV blend?
It is a combination research product with 500 mcg each of BPC-157 (in arginine-salt form) and KPV (an alpha-MSH tripeptide). It is studied in repair-signaling and melanocortin-pathway research and supplied for research use only.
What is the “arginine salt” form of BPC-157?
It is a salt variant of the BPC-157 peptide, paired with arginine. Salt forms are chosen for handling and stability; the peptide itself is the same BPC-157 sequence.
Why combine BPC-157 with KPV?
BPC-157 research centers on repair signaling and KPV on NF-kB-pathway signaling. Pairing them lets researchers study the two complementary pathways in one preparation.
Are the two peptides joined together?
No, they are two separate molecules combined in the same preparation, each keeping its own structure and targets.
How much of each peptide is provided?
Each unit contains 500 mcg of BPC-157 (arginine salt) and 500 mcg of KPV.
Is this blend FDA approved?
No, it is not FDA approved. The material here is a research-use-only preparation, not for human or veterinary use.
How should it be stored?
Keep the powder frozen at -20°C and protected from light. Once reconstituted for research, store at 2-8°C and use within about two weeks.
How is quality verified?
Each component is tested to ≥99% purity by reverse-phase HPLC with mass-spec identity confirmation by an independent lab, and each batch ships with a certificate of analysis.
