Authenticity

Verify Your Lot

Every vial we ship is genuine, sealed Hospira stock. Since July 11, 2026, we log every lot number that enters our inventory. Enter the lot number printed on your vial to confirm it passed through Gridline BAC.

Dashes, spaces, and capitalization don't matter.

We don't have that lot on file

This can happen with a typo — or with stock shipped before we began logging lot numbers on July 11, 2026. Double-check the number against the label — or send us a photo of your vial and we'll verify it manually within 1 business day.

Verification confirms that a lot number was received into Gridline BAC inventory through legitimate US distribution. Lot logging began July 11, 2026; products shipped earlier may not appear. This is a chain-of-custody record maintained by Gridline Holdings LLC, not a certification by the manufacturer. Products are for laboratory and research use only.
