How it's made
Four steps, all of them in the USA
Most sellers in this market buy finished material overseas, repackage it and attach whatever certificate came in the box. Every lot here is made in the United States and tested before release — which is why we can stand behind a purity number.
01
Solid-phase synthesis
Fmoc chemistry on automated synthesizers. Resin, coupling reagents and amino acids are lot-tracked from receipt.
02
Preparative HPLC
Crude peptide is cleaved, precipitated and purified on reverse-phase C18. The peak is cut narrow and the shoulders discarded.
03
Identity & purity
Analytical HPLC for purity, ESI-MS for identity. Both traces go on the certificate — not a summary of them.
04
Lyophilization & fill
Vacuum-dried, filled into argon-flushed amber vials, capped and sealed. Lot number carried through to the label.

Volume pricing
The price drops as the order grows
Breaks are automatic and applied per SKU in the cart. No codes, no negotiation, no sales call to find out what something costs. Above 500 units of one SKU we quote against your specification.

Lot traceability
The certificate matches the vial in your hand
Every vial carries a lot number. Enter it and you get that lot's actual chromatogram and mass spectrum — not a representative example, not a PDF from whoever made it two years ago.
