About Oxytocin

Oxytocin is a nonapeptide hormone produced in the hypothalamus and released from the posterior pituitary, signaling through the oxytocin receptor. It is well known for its roles in smooth-muscle contraction and social bonding, making it a widely used tool in neuroendocrine and behavioral research models.

Researchers examine oxytocin in models of social behavior, stress and attachment signaling, smooth-muscle physiology, and neuroendocrine regulation. It is supplied as a lyophilized powder intended for reconstitution in suitable solvent under controlled laboratory conditions, tested to ≥98% purity with a certificate of analysis available on request. This material is sold strictly for research use only.
