Format: 500 mcg BPC-157 (arginine salt) + 500 mcg KPV per unit · Purity: ≥99% by reverse-phase HPLC · Identity: ESI-MS confirmed
This blend combines two peptides with complementary research profiles: BPC-157, in its arginine-salt form, and KPV, the small anti-inflammatory alpha-MSH fragment. Each unit provides 500 mcg of each. The arginine-salt form of BPC-157 is a salt variant chosen for handling; KPV adds a distinct anti-inflammatory-signaling angle to the repair-focused BPC-157.
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 peptide with an anti-inflammatory one.
- BPC-157 repair. BPC-157 is studied in tissue-repair and gastrointestinal research [PMID: 30915550].
- BPC-157 angiogenesis. Its angiogenesis and nitric-oxide signaling is an active area [PMID: 41155565].
- KPV anti-inflammatory. KPV is the alpha-MSH C-terminal fragment studied for anti-inflammatory activity [PMID: 12750433].
- KPV intestinal models. It has been studied in murine inflammatory-bowel research [PMID: 18092346].
- Combined rationale. Bringing repair and anti-inflammatory 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.
Storage and Handling Guide
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 is published for 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 and anti-inflammatory 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 anti-inflammatory 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 has a published certificate of analysis.
