Intranasal Administration
Delivery via the nasal mucosa — used for peptides like Selank, Semax and certain oxytocin protocols where CNS access matters.
Definition
Intranasal administration delivers the dose to the richly vascularised nasal mucosa, bypassing first-pass metabolism and — for small peptides — providing direct access to the central nervous system via the olfactory and trigeminal pathways. It's the standard route for Selank and Semax; other peptides may be formulated intranasally when CNS effects are the goal.
