About this compound
Oxytocin
Neurohypophysial nonapeptide
First disclosed
1953
Oxytocin is a nine-amino-acid neurohypophysial peptide that acts on the oxytocin receptor — one of the first peptides ever chemically synthesised. It remains a standard reference ligand in neuroendocrine and receptor-signalling research.
Oxytocin-receptor agonism is studied in vitro for neuroendocrine signal-transduction pathways.

Oxytocin Nasal Spray is a research-grade peptide compound, supplied by MyPeptides for laboratory research use only.
Oxytocin is the nine-amino-acid neurohypophysial peptide that acts on the oxytocin receptor — one of the first peptides ever chemically synthesised and still a standard reference ligand in neuroendocrine research.
This product supplies 2 mg of oxytocin as a ready-made solution in a 15 ml spray bottle, so no reconstitution is needed. Oxytocin is also available as a lyophilised vial for protocols that need a different concentration.
Keep the bottle refrigerated at 2–8 °C, tightly closed and protected from light. See the nasal-spray range for Semax, Selank, PT-141 and more. Not for human or veterinary use.

Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
