The Campaign for Personal Prescription Importation has been running this site for over eleven years with consistent content and a clear mission: protecting Americans' ability to import affordable medicines. That kind of track record is a good sign. Unlike many fly-by-night advocacy pages, this one lists a physical address, a phone number, and even names staff and board members. The site uses standard security like HTTPS and stays off blacklists.
There is one oddity: the page has a large number of hidden elements. That can sometimes be a sign of cloaking or deceptive content, but for a site built on Wix it's often just leftover design code. You should still be cautious if you're asked to donate or share personal information -- verify the organization independently. But for reading updates or sending a letter to Congress, personalimportation.org appears legitimate. Its long history and openness about who runs it make it hard to dismiss as a scam.
