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.
The half-life of VIP is 2 minutes (extremely short). This means dosing 4 times daily (nasal) or daily (inhaled) is typical to maintain stable levels. The half-life directly affects how long VIP remains active and influences optimal injection timing.
What Is the Half-Life of VIP?
The half-life of VIP is 2 minutes (extremely short). This is the time it takes for blood concentration to drop by 50% after administration.
Understanding half-life is essential for designing effective dosing protocols — it determines how often you need to administer VIP to maintain therapeutic blood levels.
What Does VIP's Half-Life Mean for Dosing?
With a half-life of 2 minutes (extremely short), VIP requires dosing 4 times daily (nasal) or daily (inhaled) to maintain stable levels. The standard dosage of 50-100 mcg per spray or 200 mcg daily inhaled via intranasal spray or inhalation accounts for this pharmacokinetic profile.
After approximately 4-5 half-lives, VIP reaches steady-state concentration — the point where the amount being absorbed equals the amount being eliminated. For VIP, this occurs within the first few days of consistent dosing.
When Is the Best Time to Inject VIP?
Optimal timing depends on your research goals. A half-life of 2 minutes (extremely short) means peak blood levels occur shortly after injection and decline predictably.
Common timing approaches: morning injection for daytime activity, pre-bed injection for overnight effects, or split dosing (4 times daily (nasal) or daily (inhaled)) for more stable levels throughout the day.
How Does VIP's Half-Life Compare to Similar Peptides?
VIP is a Neuropeptide, vasodilator, anti-inflammatory. Its half-life of 2 minutes (extremely short) positions it with a shorter duration of action compared to some alternatives in this class.
Shorter half-lives require more frequent dosing but allow for more precise control. Longer half-lives are more convenient but carry risk of accumulation.

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.
