About Peptidkauf
Peptidkauf rests on a simple idea: anyone buying research peptides should be able to see what is in the vial before buying. For every batch, the report of an independent laboratory is published on the product page, with purity, measured amount and a key to verify it at the laboratory.

Who is behind Peptidkauf
Peptidkauf is operated by ISAD E-COMMERCE Sp. z o.o., Poznań, Poland. We ship from Poland within the European Union, so orders from Germany, Austria and other EU countries involve no customs formalities. Company details are in the imprint.
How we work
Range. More than a hundred research products, each with an entry in the peptide lexicon. Testing. Every batch is analysed by an independent laboratory before sale and linked to the batch number on each vial. Content. Our texts order the evidence by level and say plainly where data are missing. Tools. We built the peptide calculator, comparisons and lab report archive because we need them ourselves.
What we don't do
No dosing or usage advice, no before-and-after images and no sales for human or animal use. The legal status page explains why.
