In the past couple years, demand has gone wild for drugs like Ozempic – and its cousins, Zepbound, Wegovy, and Mounjaro. For people who had never been able to lose weight before, suddenly the numbers on the scale were plummeting. And everybody wanted to get their hands on them. 

Now, in most industries, if a product goes viral like this, it’s a golden ticket. And thanks to government-granted monopolies designed to encourage innovation, the big drug companies behind these blockbuster injections are currently the only ones allowed to make them.

In theory, anyway. 

But, what if that explosive demand backfired, opening the door to legal knock-offs? You’ve maybe seen them - copycats advertised as the same thing as Ozempic. So, what’s the difference? And just how legal are they? On today’s show - a drug that’s changing people's lives is also challenging the traditional way we buy and sell medicine.
