What is the minimum order for wholesale peptides?

One 10-vial kit. We buy in bulk so researchers do not have to commit to a large purchase order to get wholesale pricing.

Are your research peptides made in America?

Yes. Our peptides are produced in the United States through a qualified domestic vendor chain, with traceability from batch to vial and no customs delays.

Does every lot come with a certificate of analysis?

Yes. Each production lot is tested by an independent ISO/IEC 17025 accredited laboratory by HPLC and mass spectrometry, and the lot certificate is published or supplied on request.

How fast do wholesale peptide orders ship?

Orders received by 2PM PT ship the same business day from domestic stock on flat-rate $70 two-day air.
