Oxytocin vs Selank
An educational, source-based comparison of Oxytocin and Selank — how each peptide works, what it's researched for, and what to know before going deeper.
A nonapeptide hormone produced in the hypothalamus and released from the posterior pituitary. Beyond its roles in labor and lactation, research examines central effects on trust, social cognition, anxiety, and pair bonding.
- Social cognition and autism-spectrum research
- Anxiety and PTSD modulation
- Pair-bonding and attachment models
- • FDA-approved (IV/IM) only for obstetric indications.
- • Intranasal/compounded use is off-label.
A synthetic analog of the immunomodulatory peptide tuftsin. Research suggests it modulates GABAergic and serotonergic systems and influences expression of brain-derived neurotrophic factor without the sedation or dependence profile of benzodiazepines.
- Generalized anxiety models
- BDNF expression
- Immune modulation
- Memory and learning in rodent models
- • Not FDA-approved.
- • Most studies are Russian clinical literature.
Trial-evidence rating
Educational grade reflecting how many peer-reviewed studies and FDA actions we cite for each peptide. Not a clinical recommendation.
FDA-approved with published clinical trial data.
Early-stage research; conclusions are tentative.
Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
