Well, You know there is like 20 different companies that make this stuff.
Lots of them are some really BS, and scam.
Number one rated Colon/Liver/Kidney cleanser out there right now is Colonix/Toxinout. Costs 140 bucks for one month supply.
I just received it, and will start it right away. Seens some crazy sh!t comming out of people, as they even have their full gallery online. Product was reviewed by different organizations. On every single one I found, Colonix was always #1. Did good research before ordering.
Good luck.
