Everything you need to know about ordering research compounds from Vitrapept. If your question isn’t here, email [email protected] and a person will answer.

Are your peptides third-party tested?

Yes. Every batch is independently tested by Janoshik for purity (HPLC), identity (mass spectrometry), heavy metals and endotoxins. The certificate of analysis is linked on each product and can be scanned from the label.

How fast is shipping?

Orders are dispatched within 24 hours and delivered across the EU in 2 to 4 business days with full tracking. Free tracked shipping applies over €150.

How should I store the products?

Lyophilized peptides are shipped stable at room temperature. For long-term storage keep them cool and dry; once reconstituted, refrigerate.

What does “research use only” mean?

All products are intended strictly for laboratory and research purposes. They are not for human or animal consumption and have not been evaluated by the EMA or FDA.

Which payment methods do you accept?

We support secure, encrypted checkout. Available payment options are shown at checkout.
