VIP is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Lyophilized (freeze-dried) VIP should be stored at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 4-6 weeks. Never freeze reconstituted peptides.
How Do You Store VIP?
Proper storage is critical for maintaining VIP's potency and safety. As a Neuropeptide, vasodilator, anti-inflammatory, VIP is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized VIP?
Unreconstituted (freeze-dried) VIP: Store at -20°C (standard freezer) for maximum shelf life of 12-24+ months. Keep the vial sealed and away from moisture.
Room temperature storage is acceptable for short periods (shipping) but degrades potency over weeks. Refrigerator (2-8°C) storage extends this to several months.
How Do You Store Reconstituted VIP?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted VIP. Freezing and thawing damages the peptide structure. The bacteriostatic water's benzyl alcohol preservative is what allows the 4-6 week window — sterile water would give you only days.
Keep the vial upright and away from the refrigerator door (temperature fluctuations from opening/closing).
How Do You Know if VIP Has Gone Bad?
Reconstituted VIP should be clear and colorless. If you see cloudiness, particles, or discoloration — discard it. These indicate bacterial contamination or peptide degradation.
If stored properly, degradation is gradual and may not be visually apparent. This is why the 4-6 week window for reconstituted peptides exists.
Can You Travel With VIP?
Lyophilized VIP can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted VIP is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on VIP Storage
Freeze-dried: -20°C, sealed, 12+ months. Reconstituted: 2-8°C, use within 4-6 weeks, never freeze. Source from vendors who ship with proper cold-chain packaging.

Frequently Asked Questions
What is VIP?
VIP (Vasoactive Intestinal Peptide) is a Neuropeptide, vasodilator, anti-inflammatory. Endogenous 28-amino acid neuropeptide produced in gut, pancreas, brain, and neuroendocrine tissues. It is researched for vasodilation, bronchodilation, anti-inflammatory effects, neuroprotection, lung function improvement.
What is the recommended VIP dosage?
Common dosages: 50-100 mcg per spray or 200 mcg daily inhaled administered 4 times daily (nasal) or daily (inhaled) via intranasal spray or inhalation. Cycle length: ongoing continuous therapy. Half-life: 2 minutes (extremely short). Use our peptide calculator for exact reconstitution math.
What are the side effects of VIP?
Limited clinical data. Nasal irritation possible. Short half-life limits systemic toxicity. Well-tolerated in preliminary studies.
Is VIP safe?
VIP has shown a favorable safety profile in research. Not FDA-approved. Orphan drug designation for pulmonary hypertension. FDA announced plans to remove from compounding lists. All research should follow appropriate safety protocols.
