Oxytocin is an endogenous 9-amino-acid neuropeptide (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH₂) synthesized in the paraventricular and supraoptic nuclei of the hypothalamus and released by the posterior pituitary. Best known for its role in labor and lactation, it is now one of the most extensively studied peptides in social neuroscience — modulating trust, empathy, pair-bonding, in-group affiliation and stress reactivity.
In research, Oxytocin has been investigated as a modulator of the HPA axis (dampening cortisol response to acute stressors), as an anxiolytic and pro-social agent in models of autism-spectrum research, PTSD, social anxiety and relationship science, and as a neuromodulator that potentiates positive social cue processing. Onset in reported subcutaneous and intranasal studies is rapid — measurable behavioral effects within minutes.
BioPeptideX supplies Oxytocin as a 10 mg lyophilized powder, ≥99% HPLC verified, sealed under inert atmosphere and shipped with a Certificate of Analysis. Every vial is lot-traceable — for laboratory research use only.
