Why is oxytocin usually intranasal in research?
Intranasal administration is the standard route used in the CNS literature because peripheral oxytocin crosses the blood-brain barrier poorly.
How should oxytocin be stored?
Lyophilized at -20°C, and refrigerated at 2–8°C once reconstituted. It degrades quickly at room temperature.
Is a certificate of analysis provided with oxytocin?
Yes. Every oxytocin lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
How should oxytocin be stored?
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
