OXYTOCIN FAQ
Where do I buy oxytocin peptide for research?
Oxytocin is available from Blank Peptides in 5mg vials, made in our cGMP labs in the USA and shipped with a lot-matched certificate of analysis. Like every peptide in the catalogue, this is research grade material sold to researchers, so there is no prescription process on our side. Processing time is within 1 business day.
What is oxytocin?
Oxytocin is a cyclic nonapeptide produced in the hypothalamus, with a disulfide bridge between two cysteine residues forming its characteristic ring. It has one of the longest research records of any peptide, spanning smooth muscle physiology, receptor pharmacology and a large body of social behaviour work in rodents and primates. Researchers modelling the reproductive axis often pair it with kisspeptin-10.
What purity is your oxytocin?
Greater than 99%. Identity and purity are confirmed by HPLC and mass spectrometry at our lab and again by an independent run at Freedom Diagnostics or Horizon Analytical. Every batch undergoes bacterial endotoxin testing at release. The COA is lot-specific, which matters for a cyclic peptide where ring closure affects the assay.
How much bacteriostatic water for a 5mg oxytocin vial?
0.5mL at our standard 1mL per 10mg ratio, giving 10mg/mL. Some researchers use 1mL instead for a 5mg/mL solution when small-volume accuracy matters more than concentration. Add the water against the vial wall, swirl gently, and avoid shaking; the disulfide ring does not appreciate mechanical stress.
How should oxytocin be stored?
Lyophilized and sealed at -20C, dark and dry. Oxytocin is more temperature-sensitive in solution than most of the catalogue, so once reconstituted keep it strictly at 2 to 8C and use within a short window of laboratory work. Do not leave mixed solution at room temperature between sessions.
How is oxytocin shipped?
From inside the USA with a processing time within 1 business day, in plain outer packaging with no compound names on the box. Tracking is emailed as the label prints. The lyophilized cake travels fine at ambient temperature, so domestic transit needs no cold chain.
Is research oxytocin the same as the clinical drug?
No. Oxytocin exists as an approved prescription medicine in clinical settings, but the material sold here is unapproved research grade compound intended for laboratory use only. It is not a drug, supplement or veterinary product as supplied, and it is not for human use. Treat the two as separate categories.
Can I buy oxytocin without a prescription?
You can buy this research grade material without one, because it is sold as a research chemical rather than a medicine. That distinction carries obligations: it stays in the laboratory, it is handled by someone qualified, and it is never administered to people or animals outside an approved study protocol.
