Oxytocin is a nonapeptide, a nine-amino-acid neuropeptide originally identified in the mammalian hypothalamic-neurohypophyseal system. It is a cyclic peptide stabilized by a disulfide bridge between two cysteine residues. This product is supplied as a lyophilized powder for laboratory research use.
Oxytocin has been investigated in preclinical models of social behavior in rodents. It is also studied within neuroscience and endocrinology research examining stress-axis signaling and hypothalamic-pituitary pathways. Cardiovascular research has examined its receptor pathways in isolated tissue and animal models.
Lyophilized Oxytocin 2mg should be stored frozen and protected from light to maintain stability. The product should remain in its original sealed container under these conditions. Standard cold-chain storage practices are recommended for laboratory peptide handling.
Oxytocin was one of the first peptide hormones to be chemically synthesized, a historical development that established methods still referenced in peptide-synthesis literature. Its short sequence and disulfide-stabilized ring also make it a common model peptide for studying cyclization chemistry. Oxytocin is frequently discussed alongside vasopressin, a structurally related nonapeptide, in comparative receptor-binding literature.

Independent Janoshik COA in progress – verified report to follow.
Our compounds are tested by an independent third-party laboratory, and we publish the certificate for each one in our COA library. COAs are available on request and show HPLC and mass spectrometry data.
Each COA includes: compound identity confirmation, purity percentage via HPLC, mass spectrometry verification, batch number, and testing date. All testing is performed by an independent third-party laboratory. For research purposes only.
Lyophilized (freeze-dried) peptides should be stored at -20°C and kept away from light and moisture for maximum stability. Once reconstituted, store at 4°C and use within 30 days. All compounds are shipped with appropriate packaging to maintain integrity during transit. For laboratory research use only.
Orders placed by 4PM ET are dispatched the same day, seven days a week. Every order ships from the US with tracked shipping, and your tracking number is emailed the day it ships. Most domestic orders arrive within 2–5 business days.
No. All compounds sold by Core Research Peptides are strictly for in-vitro laboratory research purposes only. They are not intended for human or animal consumption, diagnostic use, or therapeutic application. By purchasing, you confirm you are a qualified researcher using these compounds in a laboratory setting.
