- What exactly is PT-141?
- PT-141 is supplied as a defined chemical entity: molecular formula C50H68N14O10, average molecular weight 1025.2 g/mol, CAS registry number 189691-06-3. Those three values are what identify the material unambiguously — a supplier that cannot state them is not describing a characterised compound. Each batch is accompanied by a certificate of analysis carrying the same identifiers.
- How is the purity of PT-141 verified?
- Purity is determined by high-performance liquid chromatography, with identity confirmed by mass spectrometry. The stated figure for this item is 99.0%. Verification is per batch rather than per product line, which is why the lot number on the vial and the lot number on the certificate of analysis have to match — a certificate that is not batch-specific documents nothing about the vial in front of you.
- Is PT-141 available from a pharmacy, and what is the pharmacy price?
- Not this material, no. The molecule in PT-141 is authorised as a medicine under another name — Vyleesi (US) — but that authorisation covers a licensed medicinal product made, tested and released to pharmaceutical standards, prescribed for a specific indication. What is supplied here is laboratory reference material for in-vitro research: the same molecule, a different regulatory object. No pharmacy dispenses it, it has no pharmacy price, and no prescription is issued or implied.
- How should PT-141 be stored?
- Store as received: Refrigerate 2–8 °C. Lyophilised material is stable far longer than material in solution, so it is kept sealed and dry until it is prepared for laboratory work; the recommended diluent for this item is Bacteriostatic water. Protect from light and from repeated temperature cycling, and record the date the vial was opened.
- Do you ship PT-141 within Europe?
- Yes. Orders are dispatched from within Europe with tracked delivery and plain, unbranded outer packaging, which is what keeps transit times short for EU destinations. Material is labelled for laboratory research use. Delivery windows and destinations are listed on the shipping page.
