Oxytocin

Oxytocin is a nine-amino acid neuropeptide hormone produced in the hypothalamus and released by the posterior pituitary gland. Known as the "love hormone," it plays critical roles in social bonding, maternal behavior, sexual reproduction, childbirth, and lactation. Research has expanded to include its roles in anxiety, trust, empathy, and various psychiatric conditions.

Frequently Asked Questions About Oxytocin

Oxytocin is a nine-amino acid neuropeptide hormone produced in the hypothalamus, involved in social bonding, reproduction, childbirth, lactation, and emotional regulation.

Oxytocin is studied in social neuroscience, reproductive biology, psychiatric research (autism, anxiety, PTSD), maternal behavior, and trust/empathy studies.

Our wholesale Oxytocin is ≥98% pure, verified by HPLC with complete certificates of analysis.

Lyophilized Oxytocin should be stored at -20°C. Reconstituted solutions should be kept at 2-8°C and used within 7-14 days.

While structurally similar (differing by only two amino acids), Oxytocin primarily mediates social bonding and reproduction, while Vasopressin regulates water balance and blood pressure.
