- Carbetocin
- Selective oxytocin receptor agonist with deamino modification
- ~30 minutes
- Reproductive neuroscience, maternal bonding models
- Resistant to aminopeptidase degradation; 6–15× longer plasma exposure than oxytocin
- Gold standard for oxytocin-like effects with extended duration. Minimal cross-reactivity with vasopressin V1a
- Desmopressin (DDAVP)
- Selective vasopressin V2 receptor agonist
- 8–12 hours
- Pair-bonding isolation studies, V2-specific pathway mapping
- Fully resistant to vasopressinase; allows clean separation of V2 vs V1a/oxytocin effects
- Essential for vasopressin pathway control. Not an oxytocin mimic but critical for isolating oxytocin-specific outcomes
- SR49059 (V1a antagonist)
- Selective vasopressin V1a receptor blocker
- 4–6 hours
- Social cognition pathway isolation, oxytocin receptor-specific studies
- Blocks V1a without oxytocin receptor interference; eliminates vasopressin confounds
- Best tool for proving which behaviors are oxytocin-dependent vs vasopressin V1a-dependent
- Setmelanotide (MC4R agonist)
- Melanocortin-4 receptor selective agonist
- 5–7 hours
- Prosocial behavior independent of oxytocin pathways, anti-inflammatory models
- Stable peptide; works in oxytocin receptor knockout models
- Proves oxytocin-independent prosocial pathways exist. Critical for expanding social neuroscience beyond oxytocin-centric models
- Survodutide (GLP-1/GIP dual agonist)
- Dual incretin receptor agonist inducing endogenous oxytocin release
- ~7 days (once weekly dosing)
- Metabolic-social reward overlap studies, satiety-bonding research
- Triggers central oxytocin release without exogenous administration; avoids peripheral degradation
- Indirect oxytocin pathway modulation. Bypasses degradation by activating endogenous release mechanisms
- MK 677 (Ibutamoren)
- Growth hormone secretagogue (ghrelin receptor agonist)
- 24 hours
- Orexigenic-prosocial signaling, neuroprotection in aging models
- Long half-life; modulates ghrelin-oxytocin crosstalk in hypothalamus
- Neuroprotective with indirect prosocial effects. Useful for aging research where oxytocin receptor density declines
