Why PepPure
Quality you can check
Every product comes with a batch number, an analysis by an external lab and a certificate you can view before you order.
99%+ purity, always
Every batch is analyzed independently by HPLC and mass spectrometry. If a batch falls short, we don't sell it.
A COA with every product
The product page shows the certificate for the batch you will receive, not a sample report from an earlier production run.
Stored correctly
We keep stock in the Netherlands. Lyophilized peptides are kept cool and dark there, and leave in insulated packaging.
Available 24/7
