ABOUTUS
Mr Peps
Research peptides, documented and delivered properly
We are a UK-based supplier focused on high-purity peptides for laboratory use. Our customers are researchers and institutions in the UK, USA and Europe who need reliable material, clear batch paperwork and support that does not dodge the hard questions.
We do not chase trends or stock mystery blends. Each listing is tied to a defined product, traceable batch documentation where applicable, and the same care whether you order one vial or a standing restock.
How Mr Peps began
Built in the UK to strengthen peptide research
Mr Peps was founded in the United Kingdom at a time when many labs still struggled to source peptides reliably: long lead times, opaque quality data, and suppliers who treated research compounds like generic retail goods. We started with a simple idea: if peptide science is going to move forward, researchers need dependable access to well-characterised material and honest information, not just another catalogue page.
Being UK-based was deliberate. The country has a strong tradition in life sciences and academic research, and we wanted to anchor the business where we could work closely with compliance, cold-chain logistics, and the expectations of serious laboratories. From that base we grew to serve customers across Europe and the United States, always with the same goal: to remove friction from legitimate research so teams can spend less time chasing supply and more time on their work.
Increasing research using peptides means more than selling vials. It means publishing clear specifications, standing behind batch documentation, answering technical questions properly, and treating every order as part of someone's experiment. That is the standard we set when Mr Peps was created, and it is the standard we still hold today.
