A UK research peptide supplier built on transparency

Ascend Peptides UK supplies research peptides to independent researchers, private laboratories and biotechnology research organisations across the UK. Our catalogue covers single vials through to larger quantities, all shipped domestically as lyophilised powder.

Rather than asking you to take quality on trust, we send samples to Janoshik for independent third-party testing and publish the batch-specific Certificates of Analysis that come back, covering HPLC purity and LC-MS identity. Where a batch has been verified, you can review its documentation before you place an order.

All products are supplied strictly for laboratory research use and not for human use. You must be 18 or over to purchase. Learn more about research peptides in the UK.
