VIP (Vasoactive Intestinal Peptide) vs Gonadorelin
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 →Gonadorelin
Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural hormone production.

| Aspect | VIP (Vasoactive Intestinal Peptide) | Gonadorelin |
|---|---|---|
| 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. | Binds to GnRH receptors in the pituitary gland, triggering pulsatile release of LH and FSH. This stimulates testicular or ovarian function and natural sex hormone production. |
| Typical Dosage | Intranasal: 50-200mcg 1-3 times daily for chronic inflammatory conditions. Some protocols use subcutaneous administration. Dosing varies by condition. | Men: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies. |
| Administration | Intranasal is most common for inflammatory conditions. Subcutaneous injection also used. Must be stored cold and protected from light. | Subcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy. |
| Side Effects | May cause nasal irritation, flushing, headache, or temporary diarrhea. Generally well-tolerated at standard doses. | Headache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated. |
