How do I send peptides for testing from Portugal?
The short answer
Portugal to Spain is an intra-EU shipment across a land border: CTT or any courier, no customs declaration, no duties. Order first to receive the address and a task reference, then send the whole unopened vial in its original packaging at ambient temperature. Typical courier transit is one to three working days.
In detail
Iberian neighbours have the simplest logistics after Spain itself: road courier, a day or two in transit, and no administrative step at any point.
Lyophilised peptide travels at ambient temperature without loss over normal transit times, so a standard tracked parcel is the right service. Pack the vial in a rigid box with padding.
Keep the tracking number until the certificate is published; the task reference issued with your order is what links the parcel to the result.
