VIP (Vasoactive Intestinal Peptide) vs HGH Fragment 176-191
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 →HGH Fragment 176-191
HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

| Aspect | VIP (Vasoactive Intestinal Peptide) | HGH Fragment 176-191 |
|---|---|---|
| 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. | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. |
| Typical Dosage | Intranasal: 50-200mcg 1-3 times daily for chronic inflammatory conditions. Some protocols use subcutaneous administration. Dosing varies by condition. | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. |
| Administration | Intranasal is most common for inflammatory conditions. Subcutaneous injection also used. Must be stored cold and protected from light. | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. |
| Side Effects | May cause nasal irritation, flushing, headache, or temporary diarrhea. Generally well-tolerated at standard doses. | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. |
