For years at the height of his Apprentice fame the appeal of living, dressing, eating and smelling like Donald Trump showed few limits.

There were Trump steaks, Trump deodorant, Trump shoes, Trump vodka, Trump ties and, bizarrely, a Trump-branded urine test.

In 2009, Trump reported that his licensing partners sold US$215 million worth of Trump-licensed goods across the world, according to the Washington Post.

Trump Network, a vitamin company, reportedly sent customers urine-sample kits branded with a Trump logo.

"Take a snapshot of the most critical metabolic markers in your body's natural waste fluids," the website said.

When Trump joined the presidential race in 2015 he had 19 remaining licenses paying some US$2.4 million a year, according to the Washington Post.

But the paper, which worked with the Investigative Reporting Workshop at American University, found that just two were still in existence.

They were a Panamanian firm selling Trump bed linens and homeware and a Turkish company selling Trump furniture.

A Trump Organisation did not response to a request for comment.
