- This table compares intranasal oxytocin administration against alternative trust protocol approaches. Showing dose ranges, mechanisms, timing requirements, and research application clarity.
- Intranasal Oxytocin
- 24–40 IU, single dose
- Direct CNS penetration via olfactory/trigeminal pathways; amygdala modulation + mPFC connectivity
- 45–60 min before interaction
- Strong (multiple RCTs, fMRI validation)
- Gold standard for trust research. Mechanistically clear, reproducible, time-limited effect
- Oral Oxytocin
- 50–100 IU
- Degraded by gastric enzymes; minimal CNS penetration
- N/A (ineffective)
- Weak (null results in controlled trials)
- Not viable. Peptide structure destroyed in GI tract before absorption
- Sublingual Oxytocin
- 10–20 IU
- Partial buccal absorption; inconsistent CNS delivery
- Variable (30–90 min)
- Limited (small pilot studies only)
- Unproven. Absorption bypasses first-pass metabolism but CNS penetration unconfirmed
- IV Oxytocin Infusion
- 1–5 IU/hour
- Peripheral receptor binding; blood-brain barrier limits CNS access
- Continuous during protocol
- Minimal for trust (used clinically for labour induction)
- Inappropriate for behavioural research. Peripheral effects without reliable central modulation
- Placebo Control
- Saline spray
- No receptor binding
- Same as active condition
- Required in all valid protocols
- Mandatory comparison. Oxytocin effects are subtle and context-dependent, requiring blinded placebo arm
- The intranasal route is the only delivery method with consistent evidence for CNS penetration and behavioural trust modulation. Alternative routes either fail to reach central receptors or produce inconsistent, unreplicable results.
