I looked into that more than a year ago, I thought I could buy it cheaper and then may be sell it for cost plus shipping. After reading the rules, it said you were not allowed to sell it for less.
So this time I found seatwo, who uses it a lot, and bought 12 bottles, paid the 12 bottle price and we each took 6. In this case I am not a distributor.
Andreas says to look into colosan powder (cheapest) and they make the capsules oxyflush. Look under suppliers http://www.ener-chi.com Once in awhile people have written about Mag07, but lately I have not heard about it anymore.

If you body accepts fiber products, you could look into P&B shakes, see under FAQ at top of page. When I started out I did the 3 weeks 1 tsp Epsom Salts in the morning. This comes from Andreas Moritz , you can do it ~3x a year. He says it works, but may be it is too cheap and most people rather buy other products. Also not everyone like ES, so you kind of have to read everything and make up your own mind. I like ES, so I have no problem with it.
