Every day in the US, hundreds of thousands of people have to make decisions about their health. Treating diseases. Managing pain. It can be scary, and it can be life-changing. But what happens if you’re offered a supposed miracle cure, and you end up worse off than before?

In a new podcast from Wondery, patients in search of a miracle cure end up in critical condition. The race is on to find out what went wrong before more people get hurt. The trail leads back to a medical company with slick marketing and a charismatic CEO. And to a multibillion-dollar stem cell industry where greed and desperation collide. Laura Beil, the award-winning host and reporter of “Dr Death,” returns for this six-part investigative series from the makers of “Dirty John” and “The Shrink Next Door.” Bad Batch will explore the multi-million dollar underregulated industry of stem cell therapy where corporate greed and patient desperation collide. It’s an industry that claims to treat pain, autoimmune diseases, infections and even autism. It’s a cautionary tale, and an important listen, and we've got a preview of it for you.  Listen now at wondery.fm/BadBatchSelfie.
