It looks like a website that sells DVDs and books. Which particular DVD or book is it that reveals St. Germain's secret formula?

On the other hand, I read somewhere that St. Germain had a ritual for immortality which involved a 50-day fast (not sure if it also used an "elixir of life"). At the end of the fast, one's old teeth and hair would fall off and new ones would grow in their place. Old skin would peel off and new skin would appear from underneath the old, like a snake that's shedding off its skin. The physical body would literally revert to that of an 18-year-old. It was an extremely difficult fast that only very few advanced adepts like St. Germain could do. And this was to be done every 50 years for as long as you wanted to remain in the physical plane as an "immortal".
