I enjoy a sauna, and like the very clean way I feel afterwards, but the Purif didn't do much for me. I'm a bit of an exercise freak so, taking a sauna and running was no big deal for me. I've never smoked, don't drink, and have never taken any drugs beyond an occasional painkiller, so maybe I wasn't 'toxic' enough. My dad said there's no proof that the Purif can deliver what's promised. He also said that LSD isn't stored in the body - it's ingested, does what it does, and is excreted in a matter of hours, so Hubbard's talk about it being stored in body fat is simply incorrect. He also said that there is no known clinical reason to give anyone such high doses of Niacin; as even a person with a severe Niacin deficiency (Pellagra) doesn't need anything like the dosage used in the Purif.
