Oxytocin Nasal Spray
Pre-mixed oxytocin solution in a 15 mL metered nasal pump
- FormAqueous solution, 15 mL amber bottle with metered nasal pump
- Research areasIntranasal delivery and nose-to-brain transport, social behaviour paradigms, formulation stability
Supplied for laboratory research use only. Not for human or veterinary use, and not intended to diagnose, treat, cure or prevent any disease.
Overview
This product presents synthetic oxytocin as a ready-mixed aqueous solution in a 15 mL amber bottle with a metered nasal pump. The peptide is identical to the material in our lyophilized vials — the cyclic nonapeptide with a Cys1–Cys6 disulfide bridge — but supplied pre-dissolved so that investigators studying intranasal delivery can work with a consistent, prepared article rather than reconstituting powder and filling bottles themselves.

Questions about Oxytocin Nasal Spray
How much oxytocin does each bottle contain?
Both options hold 15 mL of solution; one is filled with 10 mg of oxytocin and the other with 20 mg, giving roughly 0.67 mg/mL and 1.33 mg/mL. Using the conventional 1 IU ≈ 2 µg conversion, those fills correspond to approximately 5,000 IU and 10,000 IU respectively.
Is the peptide the same as the lyophilized vials you sell?
Yes. The same ≥99% HPLC-purity synthetic oxytocin is used, with identical CAS number, formula and sequence. Only the presentation differs — this arrives pre-dissolved in a metered nasal pump rather than as a dry cake requiring reconstitution.
Do you supply a certificate of analysis?
Each bottle traces to a lot-matched COA covering the peptide used in the fill, with HPLC purity of ≥99% and mass-spectrometric identity confirmation. Quote the lot number on the bottle label when requesting it and we will send the matching document.
Why is intranasal oxytocin such a debated research topic?
Central penetration after nasal delivery is small and hard to measure directly, and behavioural effect sizes in social paradigms tend to be modest. Differences in device, deposition, volume and formulation plausibly account for much of the inconsistency between published studies, which keeps the methodology under active discussion.
How should it be stored and how long is it usable?
Keep it upright at 2–8 °C away from light and never freeze it. Solution-phase oxytocin degrades faster than lyophilized powder, so define an in-use period in your protocol, verify concentration analytically for long studies, and discard the bottle if the liquid clouds or discolours.
Can I use this personally because it looks like a normal nasal spray?
No. The familiar packaging does not change what this is: a research chemical supplied for laboratory investigation only. It is not a medicine, supplement or veterinary product and is not intended, labelled or approved for administration to humans or animals.
