Oxytocin
Pitocin / OT / The Love Hormone / The Bonding Hormone
A nine-amino-acid neuropeptide produced in the hypothalamus and released by the posterior pituitary. FDA-approved (IV) for labor induction and postpartum hemorrhage. Intranasal oxytocin is used off-label and in biohacking for social bonding, anxiety reduction, trust enhancement, and emotional regulation. Plays roles in pair-bonding, empathy, stress reduction, and even wound healing.

Evidence Overview
Strength of evidence across clinical, expert, and experimental lanes.
How Oxytocin is dosed in practice
Usually taken as a nasal spray. Typical range: 20–40 IU intranasal. Half-life: 3–5 minutes (IV); longer intranasal (central effects). Each card gives the dose, frequency and duration from one evidence lane: Clinical (human trials), Expert (practitioner protocols) or Experimental (early or animal data). These ranges describe what has been studied or used; they are not a prescription.
Work out the units to draw with the reconstitution calculator, how long a vial lasts with the vial duration calculator, and how levels fall between doses with the half-life calculator.
Intranasal oxytocin is not FDA-approved; the approved product is IV or IM for labor and postpartum bleeding. Acute studies typically gave 24 IU once. A 24-week phase 2 trial in children with autism (2021) found no benefit, and large replications (2020, 2026) found no meaningful effect on trust.

- Phase 2 trial in children with autism (2021)
- Large replication studies (2020, 2026)
Increasingly used in integrative psychiatry for social anxiety, relationship therapy, and trauma processing. 20–24 IU intranasal 30 minutes before therapy sessions or social events. Some practitioners prescribe daily use for autism spectrum or attachment disorders. Effects are subtle — not a 'love drug' but a social salience enhancer.
- Integrative psychiatry protocols
- Autism spectrum social intervention research
- Couples therapy augmentation studies
Biohacking community uses intranasal oxytocin for social confidence, deepening emotional connection, and reducing social anxiety. Users report warmer social interactions and reduced defensiveness. Effects are subtle and context-dependent. Nasal spray formulations widely available from compounding pharmacies.

Oxytocin: common questions
What is Oxytocin?
A nine-amino-acid neuropeptide produced in the hypothalamus and released by the posterior pituitary. FDA-approved (IV) for labor induction and postpartum hemorrhage.

Plays roles in pair-bonding, empathy, stress reduction, and even wound healing.
How is Oxytocin dosed?
Oxytocin is usually taken as a nasal spray. Typical range in DoseCraft's library: 20–40 IU intranasal. Clinical (human trials): 24 IU intranasal single dose in most studies; up to 48 IU/day in a 24-week autism trial; Single dose 30–45 min before testing; daily in longer trials; Single doses; up to 24 weeks. Expert (practitioner protocols): 20–40 IU intranasal; Once daily or situationally; 4–8 weeks or as-needed. Experimental (early or animal data): 24 IU intranasal before social events; As needed or once daily; Ongoing or situational. These ranges describe what has been studied or used; they are not a prescription.
Is Oxytocin FDA-approved?
Yes. Oxytocin is an FDA-approved prescription medicine; uses outside its approved indication are off-label.
What is the half-life of Oxytocin?
DoseCraft's library lists a half-life of 3–5 minutes (IV); longer intranasal (central effects). Half-life sets how often a compound is dosed and how long it takes to clear: about five half-lives.
Who should not use Oxytocin?
Listed contraindications: Nasal congestion or sinusitis (reduces intranasal absorption); History of water intoxication (oxytocin has antidiuretic effects); Pregnancy (except under obstetric supervision for labor).
