I am not sure what company makes them, but if you search the web you can find a lot of retailers. I think they are very effective. They have drawbacks. They are longer than most paraliminals. They also require more listening. ON the postive side, you don't have to make a conscious effort for change. The stories are meant to overload the conscious mind, so as it will no be a block in your change. Their is a small variety of HPP tapes from procastination, money, relationships, time-management, self-esteem, communication, positive self-image.

I have noticed they are more of a programing. whereas paraliminals are a deep learning. Once you stop listening to HPP the benefits slip away unless regular conditioning is made.
