HGH Fragment 176-191 vs VIP (Vasoactive Intestinal Peptide)

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

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.

Side-by-Side Comparison

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