Description
Oxytocin is a nine-amino-acid hormone produced in the hypothalamus and one of the most studied neuropeptides in behavioral science. Limitless Life Nootropics supplies it in 5mg and 10mg vials, made in the USA.
What Is Oxytocin?
Its structure was determined and synthesized by Vincent du Vigneaud in 1953, the first peptide hormone ever made in a lab, earning him the Nobel Prize in Chemistry. The sequence is Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, with a disulfide bridge between the two cysteines forming a ring.
The hormone is released from the posterior pituitary and acts on the oxytocin receptor. It is well known for its roles in childbirth and lactation, and research has also explored its effects on social bonding, trust, stress responses, appetite and pain.
Premium lyophilized and Non-Lyophilized grades are offered in 5mg and 10mg sizes.
Research Applications
Published preclinical work has examined this peptide across several areas of investigation:
- Social bonding and recognition
- Stress and anxiety-like behavior
- Uterine contraction and lactation
- Appetite and metabolic regulation
- Oxytocin receptor pharmacology
Researchers can review peer-reviewed studies on this compound through the National Library of Medicine (PubMed) database.
