Is PT-141 legal to buy in the UK or US?

Yes — but only with a prescription, through a regulated route. PT-141 is a prescription-only medicine in the UK and the US. It is the active ingredient in Vyleesi. The lawful way to buy it is a route where a licensed prescriber makes the decision and a registered pharmacy dispenses — check any seller against the official registers before paying. Anything sold without a prescription, including "research-grade" versions of the same molecule, sits outside that system.

How does PepCred check PT-141 sellers?

Every seller is checked against official registers — Companies House, the GPhC and CQC in the UK, the FDA and state records in the US — and any published regulator action is shown with the document linked. Scores state how much matched; a warning outranks everything else.

B. Company and legal routeNo complete prescription route is confirmed hereTap for details

Company identity alone is not a legal prescribing or dispensing route.

C. Exact purchaseCheck your own order when it arrivesTap for details

For a licensed medicine, check the packaging and supply chain against the prescription, and look for any recall or falsification notice. A research-material HPLC report is not the relevant proof.

Research evidence context: Human studies are present. Research evidence level A. A human study does not by itself establish approval, effectiveness or a safe buying route; animal and in-vitro findings are kept separate.

Market surveillance: sites listing PT-14134 not recommendations

These records help identify risky listings. They are deliberately unranked and are not places PepCred recommends buying from.
