PURITY YOU CAN VERIFY

Every batch is independently HPLC-tested before it leaves either coast, with mass-spec confirmation on flagship compounds. The Certificate of Analysis ships in the box and lives in your account dashboard — no email requests, no delays. Lot numbers trace back to the original synthesis batch and the test instrument that signed off on it.

TWO-COAST DISPATCH

Tampa, Florida handles every order east of the Mississippi; our California warehouse covers everything west. Orders placed before 3 PM local ship the same business day, which means most researchers see delivery in 1-3 days without paying for expedited service. Cold-chain handling is standard on every shipment regardless of dollar value.

AMERICAN SYNTHESIZED, AMERICAN TESTED

USA Warehouse Supply Co is American owned, with U.S.-based synthesis partners and U.S.-based analytical labs. Nothing is drop-shipped from overseas. Every Certificate of Analysis carries a domestic lab signature you can phone-verify, and our compliance team can produce chain-of-custody documentation on request.

We ran independent HPLC on three lots of their BPC-157 before approving them as a vendor. Purity numbers came back within 0.4% of their CoA.

Same-day shipping from California means our protocol timelines don't slip waiting on materials. Compliance documentation is the cleanest I've seen from a domestic supplier.
