→ Common Intranasal Peptides
Semax
A synthetic analogue of ACTH studied for cognitive support and neuroprotection. One of the most commonly researched intranasal peptides.
Selank
A synthetic analogue of tuftsin researched for anxiolytic and nootropic effects. Often paired with Semax in intranasal protocols.
Oxytocin
A neuropeptide studied for its role in social bonding, trust, and stress regulation. Intranasal delivery provides direct access to CNS pathways.
PT-141
A melanocortin receptor agonist researched for its effects on sexual function. Originally developed as an intranasal compound.

Frequently Asked Questions

What diluent should I use for intranasal peptides?

Sterile 0.9% sodium chloride (saline) is the standard choice for intranasal peptide preparation. It is isotonic with nasal tissue, well-tolerated, and available in single-use preservative-free formats. Bacteriostatic water is not recommended for intranasal use — the benzyl alcohol preservative can cause nasal irritation.

How much does a nasal spray pump deliver per spray?

The Spirare Supply atomizer delivers roughly 0.1mL (100µL) per spray.

What is a typical intranasal peptide dose?

Dose ranges vary by peptide and research protocol. Always reference published research or established community protocols for the specific peptide you are working with.

How should I store a reconstituted peptide vial?

Reconstituted peptides should be stored refrigerated at 2–8°C. Minimize freeze-thaw cycles and keep vials away from light. Use within the timeframe appropriate for the specific peptide.
