KPV tripeptide nasal spray for mucosal inflammation and gut-barrier research.
KPV (Lys-Pro-Val) is the C-terminal tripeptide of α-MSH, studied for its potent anti-inflammatory effects on mucosal surfaces, the gut lining, and the skin without α-MSH's pigmentation activity.
Each PeptidePen is filled in a controlled cleanroom and sealed with tamper-evident packaging. Batch documentation includes identity confirmation, HPLC purity analysis and concentration verification. Strictly for in-vitro research — not for human or veterinary use.

KPV nasal spray is an innovative formulation that combines the KPV peptide with a delivery system designed for application through the nasal passages. This specialized format enables fast and efficient absorption through the nasal mucosa, providing a direct pathway for localized interaction.
During the development of the KPV nasal spray, particular focus has been placed on optimizing delivery to immune-active areas within the nasal and sinus cavities. This targeted approach is explored for its potential to support local immune balance in regions commonly exposed to environmental stressors.
The formulation is designed to maintain peptide stability during storage and use, while ensuring a gentle profile suitable for repeated application.
KPV nasal spray is being explored for its interaction with the immune system through several mechanisms, particularly related to its anti-inflammatory and antimicrobial properties:
Inflammatory response modulation — KPV is associated with influencing the production of inflammatory mediators, supporting a balanced response and contributing to overall immune function
Antimicrobial activity — Research suggests that KPV may exhibit activity against certain microorganisms, including bacteria and fungi, supporting natural defense mechanisms
Support of regulatory T-cell activity — KPV is being studied for its potential role in supporting regulatory T-cells, which are important for maintaining immune balance and preventing excessive immune reactions
KPV nasal spray is associated with:
Supporting local immune function in the nasal and upper respiratory tract
Promoting balanced inflammatory processes in the airways
Supporting the body's response to external environmental factors
Contributing to respiratory comfort and mucosal health
Providing rapid local availability due to efficient absorption through the nasal mucosa
A commonly used approach:
1 spray in the morning
1 spray in the evening
Modulates NF-κB inflammatory cascade
Supports gut-mucosa and intestinal barrier
Reduces sinonasal inflammation in research models
Pairs well with BPC-157 for GI protocols
