Oxytocin (10mg)

Nonapeptide hormone and neuromodulator. Oxytocin is a nine-amino-acid hormone made in the hypothalamus and released from the posterior pituitary. Its peripheral roles in labour and lactation are well established; the research interest today is in its central effects on social recognition, trust, bonding and anxiety, where it acts as a neuromodulator.

Social behaviour: bonding and recognition circuits. Anxiety research: amygdala fear-response modulation. Reproductive physiology: uterine and mammary receptor pharmacology. Autism research: intranasal trial history. Intranasal oxytocin has been tested in autism, social anxiety and schizophrenia with variable results and questions about brain penetration. Rodent studies map pair-bonding and maternal behaviour circuits. It remains a standard tool in social-neuroscience research.

Intranasal oxytocin studies reported changes in trust, social recognition and anxiety measures with inconsistent replication; obstetric use is long established.

Registered obstetric use carries a defined safety profile; intranasal research reported headache and nasal irritation. Cardiovascular effects with rapid intravenous dosing are documented in that setting.

Published Oxytocin studies specify their own amounts and routes, and those vary by model and endpoint. Peptide Aus products are supplied for in-vitro laboratory research, so we do not provide dosing, cycle or usage guidance for people. For laboratory preparation, the reconstitution calculator converts vial size and water volume into concentration and syringe units.

Structurally similar nonapeptides with different receptor profiles; vasopressin acts on blood pressure and water balance.

Add about 2 mL of bacteriostatic water slowly down the inside of the vial and swirl gently; do not shake. 10mg in 2 mL gives 5 mg/mL. Refrigerate at 2–8 °C after reconstitution and use within 8–12 weeks. The calculator has this vial preset.

Lyophilised: −20 °C, sealed, away from light and moisture. Reconstituted: 2–8 °C, used within 8–12 weeks, never frozen.

Oxytocin is a Schedule 4 prescription-only medicine in Australia when supplied as the registered injection for obstetric use. Research-grade oxytocin powder is not that product and is not approved for human use. Peptide Aus supplies it for in-vitro laboratory research only.
