Digestive problems? Professor Phardtpounder will clean your ass out in NO TIME. Hot going in? That just means it's working. Rapidly onset bubble-gut? That means it's working. Burning sensation upon exit? That's means it's done working. Honestly though, this is a tasty sauce with almost a mustardy flavor. Not super hot, somewhere in between medium and hot. OH, it comes in a flask bottle. Can't beat that.
