How do I send peptides for testing from Poland?
The short answer
Poland to Spain is an intra-EU shipment: InPost, Poczta Polska or any courier, no customs declaration, no duties. Create the order first so the vial travels with a task reference, then send the whole unopened vial in its original packaging at ambient temperature. Typical courier transit is two to four working days across Europe.
In detail
No customs form is needed inside the EU, so the distance is the only difference from a domestic parcel. A tracked courier service is worth the small premium over untracked post for a sample that cannot be replaced.
Lyophilised peptide is stable at ambient temperature for normal transit times; a standard parcel with padding and a rigid outer box is the right choice.
Send the vial unopened, with its label and lot number, and keep the tracking number until the certificate is published under your task reference.
