Questions about an order, a compound, a certificate, or something we do not stock yet. We aim to reply within one business day.

Before you write

Our FAQ covers storage, reconstitution, testing and shipping. Shipping & Delivery covers tracking and dispatch times, and Returns & Refunds covers anything that arrived wrong. If a compound is not in the catalog, use the suggest-a-peptide prompt at the bottom of the Catalog.

Writing about an existing order? Include your order reference — the eight characters at the top of your confirmation email — and, if something arrived damaged or incorrect, photographs of the parcel and the vial.
