Oxytocin
OT; Pitocin/Syntocinon (medical brand names)
A nine-amino-acid peptide hormone made in the hypothalamus and released by the posterior pituitary; acts on oxytocin receptors to drive uterine contraction and milk let-down, and is studied as a central modulator of social behaviour.
Well-established as an approved obstetric drug (labour induction/augmentation, postpartum bleeding, milk let-down). Its off-label 'biohacking' use as intranasal spray for trust/bonding is experimental, with mixed and often non-replicated human data.
- Approved: induction/augmentation of labour and postpartum haemorrhage (clinical, supervised)
- Approved: promotion of milk let-down
- Research only: intranasal effects on social cognition, trust and bonding
Educational overview only — no dosing instructions in the public hub. Approved obstetric use is a hospital-administered, clinician-controlled IV/IM medicine; intranasal social use is off-label/investigational.
Medical IV use can cause uterine hyperstimulation, fetal distress and water intoxication/hyponatraemia if misused — a prescription-only, monitored setting. Self-administered intranasal use is unvalidated for safety or efficacy; sourcing/purity is an added practical risk.
Pharmaceutical oxytocin is a regulated prescription product; any non-pharmacy 'research' material should have a third-party CoA (purity + quantification + MS) as the minimum verification.
Approved prescription medicine for its obstetric/lactation indications in the EU, UK, US and elsewhere; outside those indications it is off-label, and non-pharmacy peptide material is sold research-use-only (RUO), not for human use.
