PT-141 — frequently asked questions

No. PT-141 is supplied strictly as a laboratory research reagent. It is not a drug, supplement or medical device, and it is not for human or veterinary use, diagnostic use, or any form of in-vivo administration. Purchasers confirm they are qualified researchers handling the material in a controlled laboratory setting.

Each lot of PT-141 is manufactured to 99.92% purity and verified by an independent third-party laboratory using HPLC and mass spectrometry. The batch Certificate of Analysis for the current lot is viewable on this page before you order.

PT-141 is supplied in 10 mg lyophilised vials. Multi-vial quantities receive an automatic volume discount at checkout: 8% on 3 vials, 15% on 6 and 20% on 10.

Store the sealed lyophilised vial at -20°C and protect it from light. For research handling, allow the vial to reach room temperature before reconstitution with bacteriostatic or sterile water, add the diluent slowly down the vial wall, and avoid shaking. Reconstituted material is typically held at 2-8°C and used within the timeframe your protocol validates.

Orders placed before 1 PM ET are dispatched the same business day via FedEx 2-Day Shipping at $14.95, free on orders over $200. Every shipment includes the batch documentation for the lot supplied.

Yes. Product information, pricing and batch documentation are gated behind a free research account, and placing an order requires that verified account so we can confirm the material is going to a qualified researcher, in line with our research-use-only policy.
