FAQ

Frequently asked questions

Every lot goes through our 6-panel testing protocol: identification by ESI-MS, purification by RP-HPLC, conformity, sterility screening, quantification of net peptide content, and LAL endotoxin screening. We publish the full analytical data in each lot's Certificate of Analysis.

Store lyophilized peptides at -20°C or below for long-term stability. Once reconstituted, store them at 2 to 8°C and use them within a timeframe suited to the compound. Avoid repeated freeze-thaw cycles. Keep them dry and away from direct light.

Ships after Thursday, November 12. Carrier transit time begins after dispatch. Standard shipping is free on orders over $150. Every order ships in insulated packaging, with ice packs when needed. After dispatch, standard delivery usually takes 2 to 4 business days within the continental US.
