Custom Peptide Quotation Request Form


Welcome to CPC Scientific's custom peptide quotation request form. We will provide you with a quotation within 24 hours.

Please submit up to ten custom peptide sequences for each request form. Our new RUSH Service is available for most peptides with the exception of certain modifications and specifications. In most cases, peptides can be manufactured within 2 weeks after a rush service has been requested.

For more complex modification requests, you may find it easier to use our Advanced Quotation Request Form
