Healthcare Facilities and Wholesalers

I am a hospital, pharmacy, or healthcare facility and want to order PreProtein for my patients or use PreProtein for inpatient care.
How can we order?

There are 2 different methods to obtain PreProtein for your hospital, pharmacy, or healthcare facility:

Method 1: We are currently accepting direct supplier agreements with hospitals and pharmacies and are able to supply them directly with PreProtein. This is a more cost-effective solution for bulk purchasing and does not require a middleman such as a pharmaceutical distributor or GPO.

Method 2: Notify your buyer that you wish to order PreProtein. Your buyer will get in contact with their respective drug distributor's (US Foods, McKesson, Cardinal, Metro Medical, etc.) account manager and request PreProtein. If you cannot locate our NDC/item number in your ordering system, please use this method.

I am a retailer, distributor, or wholesaler and want to order PreProtein for resale.
