VIP (Vasoactive Intestinal Peptide) vs Dihexa
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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 →Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.

| Aspect | VIP (Vasoactive Intestinal Peptide) | Dihexa |
|---|---|---|
| Mechanism | 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. | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. |
| Typical Dosage | Intranasal: 50-200mcg 1-3 times daily for chronic inflammatory conditions. Some protocols use subcutaneous administration. Dosing varies by condition. | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. |
| Administration | Intranasal is most common for inflammatory conditions. Subcutaneous injection also used. Must be stored cold and protected from light. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | May cause nasal irritation, flushing, headache, or temporary diarrhea. Generally well-tolerated at standard doses. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
