Frequently asked questions
What is your minimum order quantity?
MOQ depends on the peptide and specification. Pilot quantities for qualification are supported before commercial-scale supply. Send your target grade and annual volume through the RFQ form and the technical team replies within 4 business hours.
What documents come with each batch?
Each batch ships with a batch-specific certificate of analysis. HPLC chromatograms, mass-spectrometry identity data and safety documentation are available on request for qualified inquiries. Document packages are confirmed per order.
Do you offer custom synthesis and OEM?
Yes. Custom peptide synthesis from sequence, counterion exchange, lyophilization and OEM packaging are supported for qualified B2B projects. Projects are reviewed for intended use and destination-market requirements.
