PeptideSeed supplies research-grade peptides and related compounds to laboratory buyers. Thirty compounds are catalogued across seven classes, all held lyophilized, sealed under nitrogen and dispatched cold-packed from the United States.
The commitment that defines the operation is per-lot documentation. Every released lot carries a reverse-phase HPLC purity report and an LAL bacterial endotoxin assay generated against that specific synthesis, published before the lot goes to stock, and retrievable at any time by the lot number printed on the crimp label.
Publishing one certificate per product line rather than one per lot is common in this sector. It tells a buyer what a different batch looked like. We consider that a documentation failure rather than a documentation practice.
Product pages carry the chemistry: CAS number, molecular formula, molecular weight, full amino-acid sequence, appearance, solubility and storage. They carry handling guidance for laboratory work.
They do not carry dosing information, protocols, application guidance or any statement about effects in humans or animals, because those would be claims we are not in a position to make and are not permitted to make about research compounds.
Qualified purchasers aged 21 or over, buying for in-vitro laboratory research. Volume pricing, lot reservation across a run and purchase-order billing are available to verified laboratory and institutional accounts — contact the lab team.
