About KPV
KPV (Lys-Pro-Val) is a tripeptide frequently referenced as an α-MSH fragment (11–13) in experimental literature. Due to its size and stability relative to longer peptides, KPV is commonly used as a research peptide when evaluating peptide signaling hypotheses tied to melanocortin-adjacent pathways and immune/inflammation signaling markers in controlled assays.
Common research contexts include:
- In-vitro assays tracking inflammatory marker expression
- Exploratory studies of melanocortin pathway signaling
- Screening work comparing short peptide fragments for cell response profiling
For research use only. Not for human or veterinary use.

Chemical Structure
You ask,
we answer.
Are these peptides quality tested?
Absolutely. Our analytical testing is conducted by Janoshik Analytical, BioRegen, or Freedom Diagnostics, independent third-party laboratories that verify the identity, purity, and composition of our research products. All products are guaranteed to test at 98% purity or higher. Each CoA includes purity analysis, peptide sequence confirmation, date of analysis, and an endotoxin report.
What are typical delivery times?
Free UPS 2nd Day Air shipping is available when qualifying merchandise totals reach $200. UPS Ground and UPS Next Day Air Saver are also available. Please allow up to 24 hours for processing.
Every package comes with professional packaging and tracking updates via email.
How should these compounds be stored?
Our peptides are shipped in lyophilized form, which is stable at room temperature during transit. Once received, store unopened vials in a cool, dry place.
Are products stable during shipping?
Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping.
Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions.
What are your bulk ordering options?
For bulk inquiries and volume pricing, please contact us.
What is the shelf life/expiration of unopened vials?
Each lot lists a best-by/expiration on the vial label and COA. As general guidance, lyophilized peptides stored as directed are typically stable 12–24 months (often longer at –20 °C). Short shipping periods at ambient temperature are normal. Actual stability depends on sequence and storage conditions.
