Shipping policy

Products ship from the United States via tracked carriers selected by Purity Science. Orders are dispatched after compliance verification and payment terms are satisfied; you will receive carrier tracking for every shipment.

You are responsible for ensuring that someone is able to accept delivery at the address on file, and that the address is a verified licensed-practitioner or institutional premises.

Risk of loss and title transfer on tender to the carrier. Once a shipment leaves our facility and is tendered to the carrier, the chain of custody passes to the receiving practitioner or institution.

Certain peptides and investigational compounds cannot be shipped to certain U.S. states, or to addresses we cannot verify as licensed-practitioner premises. Checkout maintains a per-SKU, per-state allowlist; orders to restricted destinations are blocked at checkout with an on-screen explanation. If you believe an institutional registration or other exception applies, contact compliance@purityscience.com before placing the order.

Many peptides require refrigerated or controlled-room-temperature handling. We ship with appropriate insulation and cold packs. We are not responsible for temperature excursions caused by (a) the carrier, (b) refusal of delivery, or (c) failure to receive the package upon delivery. Visibly compromised shipments must be reported within 72 hours of carrier-confirmed delivery, with photographs of the carton, packing materials, and product (see the Refund & returns policy).

Purity Science sells exclusively to verified, U.S.-licensed healthcare practitioners and authorized licensed pharmacies, and ships within the United States only. International orders are not currently accepted.
