Oxytocin
Also Known As: Pitocin, Syntocinon, Oxytocin Acetate, Oxytocin hormone, Love hormone, Bonding hormone, Trust hormone, Neuropeptide oxytocin, Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, OXT, Uterocon, Intranasal oxytocin, Social bonding peptide, cuddle hormone, pitocin
Oxytocin is a research-grade Endogenous hypothalamic nonapeptide neurohormone targeting Oxytocin receptor studied in Sexual Health & Hormones research. It is supplied strictly for in vitro laboratory research use only - not for human or animal consumption, and not FDA-approved.
Evidence Tier: Approved Drug - FDA and/or EMA approved with robust human trial data.
The approved labor and bonding hormone; intranasal psychiatric use is investigational.

Mechanism Of Action
It is released in the brain to modulate emotional and social behaviors. It dampens the fear response in the amygdala, reducing anxiety and promoting feelings of trust and pair bonding.

Reported Research Findings
Established uterotonic and milk-ejection use. Intranasal psychiatric trials for autism and social cognition are mixed and often fail to replicate.
Safety And Handling Notes
Obstetric IV use can cause uterine hyperstimulation, water intoxication, and blood-pressure changes; intranasal use is mild.
Obstetric contraindications apply; water-intoxication risk with high doses and hypotonic fluids; intranasal psychiatric use is unapproved.
