We prefer quality over quantity. Before a peptide joins the catalogue we take the time to research it, find a dependable source and have it tested, so we are confident in its quality and that it meets our requirements. That makes our range smaller for now, but we are continuously researching and testing new peptides to widen it step by step. Our aim is a carefully chosen selection rather than simply the largest possible catalogue. We are open to feedback and encourage the conversation: every BioPeptide Club member — that is, everyone with an account — can vote from their account page for the peptide they would like to see added next.

Yes. Because the products are intended solely for scientific research, BioPeptide sells only to people aged 18 or over. When placing an order, the customer declares that they meet the minimum age requirement.
