How to Use
Simple protocol for optimal results
Prime the Spray
Before first use, pump 3-4 times into the air to prime the nozzle for consistent dosing.
Administer
Tilt head slightly forward, insert the tip gently into one nostril, and press once while inhaling slowly.
Daily Protocol
Use as directed. For best results, administer in the morning on an empty stomach. Store upright, away from heat.
Why Intranasal Delivery?
The nasal mucosa provides direct access to systemic circulation, bypassing first-pass metabolism. This means faster onset, higher bioavailability, and more predictable absorption compared to oral or sublingual routes.
