Oxytocin vs Thymulin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Oxytocin
Oxytocin is a natural hormone produced in the hypothalamus, often called the 'love hormone' or 'bonding hormone.' It plays key roles in social bonding, childbirth, lactation, and stress regulation.

Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.

| Aspect | Oxytocin | Thymulin |
|---|---|---|
| Mechanism | Binds to oxytocin receptors in the brain and peripheral tissues. Promotes social bonding, reduces anxiety and stress response, and has various peripheral effects on smooth muscle contraction. | Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age. |
| Typical Dosage | Intranasal: 20-40 IU (international units) for social/anxiolytic effects. Clinical uses (labor induction) require IV administration under medical supervision. | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. |
| Administration | Intranasal spray for behavioral effects. IV only in clinical settings. Sublingual also possible. Best used situationally rather than continuously. | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. |
| Side Effects | Intranasal: headache, nasal irritation, drowsiness. May cause over-attachment or emotional sensitivity. IV (clinical): uterine hyperstimulation, water retention. | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. |
