Oxytocin Nasal Spray
 
Oxytocin is a natural neurohormone often called the "love hormone" or "trust hormone" due to its role in social bonding, childbirth, and emotional regulation. Nasal spray delivery allows oxytocin to bypass the blood-brain barrier, making it effective for psychological and behavioral effects.
