PeptideSeed supplies research compounds for in-vitro laboratory use only. By entering this site you confirm:
Research use only. Not for human or veterinary consumption. Full terms of supply
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.
Per-lot documentation is the standard PeptideSeed is building toward: a reverse-phase HPLC purity report and an LAL bacterial endotoxin assay generated against each specific synthesis, published before the lot goes to stock and retrievable by the lot number printed on the crimp label.
That standard is not met yet. As of September 2026, PeptideSeed does not have genuine per-lot laboratory certificates published for its catalog, and does not claim otherwise. We are working directly with our supplier to obtain them, and every product and lab-report page states the current certificate status for that specific lot rather than implying results that do not yet exist.
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.
