About

Puripep operates a single laboratory in Carlsbad, California, where every peptide we sell is synthesized, lot-released and shipped. We were founded by research chemists tired of the gap between the price labs were paying for “research-grade” peptides and the actual purity of those vials. We tightened the supply chain by removing every intermediary, and we now pass the difference to you.

What we believe

Research peptides are a tool, not a product. The job of a supplier is to deliver something the lab can rely on, the same way every time, at a price that respects the size of a research budget.

That means:

• One facility. No drop-shipping. No re-labelling. Lot numbers map 1:1 to the CoA.
• ≥ 99 % HPLC identity on every release. Mass-spec, identity, purity, and where applicable endotoxin and water content.
• Flat $14.99 US shipping, free over $250, delivered in 48 hours. Plain packaging.
• If a batch fails post-release re-test, every recipient is notified and the product is replaced at our cost.

Compliance

Every product on Puripep is sold strictly for in-vitro laboratory research and authorized professional use. They are not classified as medicinal products and are not intended for human consumption, cosmetics, food additives, or any unapproved application. We reserve the right to cancel orders we believe may be used outside that scope.

We ship within the United States only.
