KPV vs VIP (Vasoactive Intestinal Peptide)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
KPV
KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.
Full details →VIP (Vasoactive Intestinal Peptide)
VIP is a 28-amino acid neuropeptide with wide-ranging effects throughout the body. It acts as a neurotransmitter, neuromodulator, and immune regulator with particular importance in gut and lung function.
Full details →Side-by-Side Comparison
| Aspect | KPV | VIP (Vasoactive Intestinal Peptide) |
|---|---|---|
| Mechanism | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. | Binds to VPAC1 and VPAC2 receptors to modulate immune responses, regulate circadian rhythms, promote vasodilation, and support barrier function in gut and lungs. Has potent anti-inflammatory effects. |
| Typical Dosage | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. | Intranasal: 50-200mcg 1-3 times daily for chronic inflammatory conditions. Some protocols use subcutaneous administration. Dosing varies by condition. |
| Administration | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. | Intranasal is most common for inflammatory conditions. Subcutaneous injection also used. Must be stored cold and protected from light. |
| Side Effects | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. | May cause nasal irritation, flushing, headache, or temporary diarrhea. Generally well-tolerated at standard doses. |
