Are your peptides tested for purity?

Yes. Every batch is independently tested by a third-party laboratory, and a certificate of analysis (COA) is published on each product page. Our peptides consistently test at 98%+ purity.

What does "for research use only" mean?

All products sold on this site are intended strictly for in-vitro laboratory research. They are not for human consumption, medical, veterinary, or household use.

How should peptides be stored?

Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term stability. Once reconstituted, most peptides should be refrigerated at 2-8°C and used within 7-14 days. See our peptide storage guide for details.

How fast is delivery?

Orders are dispatched from our UK facility. Most UK orders arrive within 1-3 working days.

What payment methods do you accept?

We accept all major debit and credit cards through our secure Worldpay payment gateway.
