Oxytocin

A workhorse obstetric medicine. Social-cognition and psychiatric uses remain experimental; intranasal research is mixed and dose/delivery are unsolved.

A nonapeptide hormone of the posterior pituitary. Peripheral receptors drive uterine contraction and milk ejection; central receptors are involved in social and stress circuitry — that second map is mostly research, not labeled use.

Labor induction and postpartum hemorrhage: strong, guideline-level. Autism, pair-bonding, and anxiety literature: heterogeneous, often small, with failed replications in several high-profile lines.

FDA-approved for labor induction/augmentation and postpartum bleeding. Other routes and indications are off-label or research.

Hospital and obstetric use for labor induction/augmentation and postpartum bleeding — a monitored infusion, not a wellness spray. Intranasal research product is a different object, usually through a trial or compounding grey zone.

Same four pathways as the Sourcing guide.

Covered in the perinatal setting as standard of care. Intranasal or psychiatric use is typically not a pharmacy benefit.

Intranasal 'bonding' and 'empathy' sprays sold online. Concentration and preservatives vary. This is not Pitocin.

Strand does not list vendors. See the grey market.

In labor, uterine tachysystole and fetal distress are the acute risks. Water intoxication with high-dose infusion is historical but real. Psychiatric self-administration has no established safety margin.
