Buying research peptides in Europe: shipping, customs and labs

Buying from the European Union is not the same as buying in the US. Many of the highest-globally-rated vendors do not ship to Europe, and those that do differ a lot on customs, timelines and guarantees. This guide is written for the European buyer.

Half the market doesn't serve you

Several of the most-cited vendors (California-based) only ship within the US: their international shipping is blocked by their payment or compliance providers. For a European buyer, their global score is irrelevant. That is why our main ranking only includes vendors with real EU operation or shipping.

Customs: who carries the risk

When a parcel crosses into the EU, it can be held at customs. The difference between vendors is who carries that risk: the best offer DDP shipping (duties paid) or free re-shipment if the parcel is held. The worst leave the problem to the buyer. It is a service criterion, not a minor detail.

EU-based vendors

Operating from inside the EU (Slovakia, Romania, Spain, Czechia) cuts customs friction and shortens timelines. In this comparison we mark each vendor's base so you can prioritise European operation if avoiding holds matters to you.

Reference European labs

The advantage of the European scene is that the reference lab, Janoshik Analytical, is in Prague. Many European vendors send every lot there and publish the verifiable report. A Janoshik CoA verifiable at source is, today, the highest trust standard available to the European buyer.

How to read our European ranking

We separate measured quality (the level and rigour of published tests) from breadth (how many lots have been analysed), and from service (refund, shipping, support). A vendor with a single impeccable analysis can have top quality even if its breadth is low: do not confuse number of tests with product quality.
