How do I send peptides for testing from Spain?
The short answer
From mainland Spain it is a domestic parcel: Correos or any courier, typically 24 to 48 hours, no paperwork. Create the order first to get the address and a task reference, then send the whole unopened vial at ambient temperature. From the Canary Islands, Ceuta or Melilla the parcel carries a customs declaration (DUA) because those territories sit outside the EU VAT area, so allow an extra day or two.
In detail
Spanish clients have the shortest path to the laboratory. A tracked Correos or courier parcel sent in the morning is usually logged the next working day, which makes the 48 to 72 hour turnaround target a realistic three-day cycle from posting to published certificate.
The Canary Islands, Ceuta and Melilla are the exception. Even though the shipment is domestic, it crosses a fiscal border and the carrier prepares a customs declaration; describe the contents accurately as a research chemical sample for laboratory analysis with nominal value.
As everywhere, send the vial whole and unopened, in its original packaging, with the task reference issued when you ordered.
