VIP (Vasoactive Intestinal Peptide) vs Epithalamin
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 →Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

| Aspect | VIP (Vasoactive Intestinal Peptide) | Epithalamin |
|---|---|---|
| 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. | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. |
| Typical Dosage | Intranasal: 50-200mcg 1-3 times daily for chronic inflammatory conditions. Some protocols use subcutaneous administration. Dosing varies by condition. | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. |
| Administration | Intranasal is most common for inflammatory conditions. Subcutaneous injection also used. Must be stored cold and protected from light. | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. |
| Side Effects | May cause nasal irritation, flushing, headache, or temporary diarrhea. Generally well-tolerated at standard doses. | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. |
