Oxytocin is a naturally occurring nonapeptide hormone and neuropeptide produced in the hypothalamus and released by the posterior pituitary gland. It has a well-characterized molecular structure featuring an intramolecular disulfide bond between cysteine residues at positions 1 and 6, forming a cyclic ring structure with a three-amino acid C-terminal tail. Heartland Bio Labs supplies synthetic Oxytocin as a lyophilized research compound of verified purity.

Oxytocin is a naturally occurring nonapeptide hormone and neuropeptide produced in the hypothalamus and released by the posterior pituitary gland. It has a well-characterized molecular structure featuring an intramolecular disulfide bond between cysteine residues at positions 1 and 6, forming a cyclic ring structure with a three-amino acid C-terminal tail. Heartland Bio Labs supplies synthetic Oxytocin as a lyophilized research compound of verified purity.

Oxytocin has been the subject of decades of research in neuroendocrinology, neuropeptide pharmacology, and stress axis biology. Research has characterized its roles in hypothalamic-pituitary-adrenal axis modulation, HPA axis signaling, and behavioral neuroscience models. It is also studied in neuropeptide receptor binding assays, rodent behavioral paradigms, and reward system biology.

This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.

How should I store this peptide?+

Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.

What should I reconstitute it with?+

Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.

How quickly do orders ship?+

Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.

Is the COA verified independently?+

Yes. Every lot is tested by HPLC for purity (target ≥99%) and mass spectrometry for molecular identity before release. The COA is generated from the actual lot data, not a generic template.

Can I get bulk or institutional pricing?+

Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
