Testing status
Not yet independently tested.Every vial is lot-numbered, so it traces back to its batch. Supplier paperwork varies from batch to batch, so email us your lot number and we’ll tell you exactly what we hold for it. We’d rather say that plainly than let this page imply more, and you can send a vial to any lab you like.

Storage and handling
Supplied lyophilised and sealed. Keep the unopened vial cool and dark — refrigeration extends shelf life and freezing is fine for long-term holding. Once reconstituted with bacteriostatic water, keep it refrigerated.
Peptides degrade through heat, light and repeated temperature cycling far faster than they do through age. That’s also why we don’t take stock back once it’s left us — we have no way of knowing how it’s been held.
What you won’t find on this page
What it does, what to take, or who should take it. Not because we’re being cagey — because this is a research compound and we’re a supplier, not a clinic. Any UK supplier printing dosing protocols under a product listing is telling you something about how carefully they treat the rest of it.

Questions
Oxytocin in the UK: what people ask
Oxytocin is a nine-amino-acid peptide with a disulfide bridge between two cysteines, forming a six-residue ring.
Is Oxytocin in stock in the UK?
Oxytocin is sourced to order rather than held on our UK shelf. It takes up to 14 working days — an order placed today is dispatched by Mon 16 Nov — and the date is shown before you pay. Delivery is £5.00 per order, tracked, and free on orders over £50.00.
What sizes of Oxytocin are available, and how much do they cost?
Oxytocin is available as 5mg at £14.00 a vial, or £110.00 for a box of 10 (£11.00 each). There is no minimum order and no account approval needed to buy a single vial.
Does Oxytocin come with a certificate of analysis?
Yes. The certificate for Oxytocin is a report from Janoshik, an independent laboratory in the Czech Republic. It's our supplier's report, with the supplier's details redacted for commercial reasons, and the vial in the certificate photo matches the vial we send. It's available on request. Every vial carries a lot number.
What is the CAS number and molecular weight of Oxytocin?
Oxytocin: CAS number 50-56-6, molecular formula C43H66N12O12S2 and molecular weight 1007.2 g/mol. It is 9 amino acids long. Reference data from PubChem. Molecular weight is for the free compound; the salt form supplied (commonly acetate) weighs more.
How should Oxytocin be stored?
Oxytocin is supplied as a lyophilised powder in a sealed vial. Keep it cool, dry and dark; refrigeration extends shelf life and freezing is fine for long-term holding. Avoid repeated warming and cooling, which degrades peptides far faster than age does.
Is Oxytocin for human use?
No. Oxytocin is supplied for laboratory research use only and is not for human or veterinary consumption. We don't give dosing, usage or health information about any compound.
