Oxytocin — Vendor Pricing & Purity Guide
Research Overview
Oxytocin is a nine-amino-acid neuropeptide produced in the hypothalamus and released by the posterior pituitary gland. Often called the "bonding hormone" or "love hormone," it plays fundamental roles in social behavior, pair bonding, maternal behavior, sexual function, and stress regulation. It is one of the most well-characterized neuropeptides in neuroscience, with research spanning over a century since its discovery in 1906.
Oxytocin has two primary modes of action: as a peripheral hormone (stimulating uterine contractions during labor and milk ejection during breastfeeding) and as a central neuromodulator (influencing social cognition, trust, empathy, and stress responses). The central effects are the focus of most current research, with intranasal administration allowing delivery to the brain via the olfactory pathway.
Synthetic oxytocin (Pitocin) has been FDA-approved for decades for labor induction and postpartum hemorrhage management. Current research focuses on its central effects for autism spectrum disorder, social anxiety, PTSD, and substance use disorders. It represents one of the most active areas of neuropeptide research, with hundreds of clinical trials ongoing worldwide.
Key Research Findings
- •FDA-approved (as Pitocin) for labor induction and postpartum hemorrhage management for over 40 years
- •Intranasal oxytocin improved social cognition and eye contact in adults with autism spectrum disorder in multiple clinical studies
- •Reduced cortisol response to social stress and improved trust behavior in human experimental paradigms
- •Enhanced fear extinction in PTSD models, suggesting potential as an adjunct to exposure therapy
- •Modulated the dopaminergic reward system, with preliminary evidence for reducing addictive behavior
- •Over 400 registered clinical trials investigating effects on autism, anxiety, PTSD, eating disorders, and schizophrenia
Research Dosage Protocols
Oxytocin is available as both injectable (Pitocin, for obstetric use) and intranasal formulations. Research on central/behavioral effects uses intranasal delivery.
Standard intranasal research doses range from 20-40 IU (International Units) administered 30-45 minutes before behavioral testing. Effects on social cognition typically peak at 45-60 minutes and last 2-3 hours.
Oxytocin is sensitive to light and temperature. Reconstituted solutions should be stored refrigerated, protected from light, and used within recommended timeframes.

Frequently Asked Questions
What is oxytocin?
Oxytocin is a neuropeptide involved in social bonding, trust, empathy, and stress regulation. It is FDA-approved for obstetric use (Pitocin) and is being researched intranasally for autism, PTSD, social anxiety, and addiction.
Can oxytocin be taken intranasally?
Yes, intranasal delivery is the standard route for central/behavioral research. It allows the peptide to reach the brain via the olfactory pathway, bypassing the blood-brain barrier.
Where can I buy oxytocin for research?
Oxytocin is available from research peptide vendors. Compare pricing in the table above.
