The topic of fecal transplants is explored in the podcast episodes, which discuss both the clinical use of this treatment and the existence of an online black market for DIY fecal transplants.

The first episode, Would You Buy Poop On the Internet?, delves into the practice of people purchasing stool samples from strangers online to self-administer fecal transplants, despite concerns from doctors about the lack of regulation and screening.

The second episode, Do gut microbes control your personality? - Kathleen McAuliffe, discusses how transferring gut microbiomes between people and animals can influence behavior and personality, highlighting the potential therapeutic applications of fecal transplants beyond their approved uses.
