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
PT-141 in the UK: what people ask
PT-141 is a synthetic cyclic peptide of seven amino acids, known in the literature as bremelanotide.
Is PT-141 in stock in the UK?
Yes. PT-141 10mg is held in our UK warehouse and dispatched within 24 hours by Royal Mail Tracked 24. Delivery is £5.00 per order, tracked, and free on orders over £50.00.
What sizes of PT-141 are available, and how much do they cost?
PT-141 is available as 10mg at £16.00 a vial, or £120.00 for a box of 10 (£12.00 each). There is no minimum order and no account approval needed to buy a single vial.
Does PT-141 come with a certificate of analysis?
Yes. The certificate for PT-141 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 PT-141?
PT-141: CAS number 189691-06-3, molecular formula C50H68N14O10 and molecular weight 1025.2 g/mol. It is 7 amino acids long. Reference data from PubChem. Molecular weight is for the free compound; the salt form supplied (commonly acetate) weighs more.
What else is PT-141 called?
PT-141 also appears in the literature as Bremelanotide.
How should PT-141 be stored?
PT-141 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 PT-141 for human use?
No. PT-141 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.
