About this compound

The bonding hormone. Enhances sexual satisfaction, reduces social anxiety, and promotes emotional connection. Available as intranasal research compound.

Product Details

Oxytocin is a synthetic peptide with a molecular weight of 1007.19 g/mol and molecular formula C43H66N12O12S2. Supplied as a lyophilised solid, each batch is verified to ≥98% purity via HPLC analysis and accompanied by a Certificate of Analysis (COA).

Oxytocin is soluble in water and dilute acetic acid. For optimal stability, store the unopened vial at -20 °C, desiccated. Stable for up to 21 days at 2–8 °C in aqueous solution under sterile conditions.

Oxytocin is a naturally occurring neuropeptide hormone produced in the hypothalamus and released by the posterior pituitary. Known as the bonding hormone, oxytocin plays a fundamental role in social bonding, sexual reproduction, and emotional regulation. Research has demonstrated its effects on enhancing sexual arousal and satisfaction, strengthening pair bonding, reducing anxiety and stress reactivity, and promoting prosocial behavior.
