Packaging
All orders are shipped in discreet, unbranded packaging with no external indication of the contents. Lyophilised peptides are stable at ambient temperature for the duration of transit; store them as described on the product page once you receive them.
Carriers
We ship via Packeta (Zásilkovna) — either to a pickup point of your choice or to your address through their partner carriers, depending on your location. All shipments include full tracking.
Customs & duties
For orders shipped outside the EU, the recipient is responsible for any import duties, taxes, or customs fees imposed by their local authorities.

- Your order arrived damaged during shipping
