I've never done a Liver Gallbladder Cleanse, but I've heard good things about it. As for colon cleansers, I would recommend OxyPowder or Colonix. In that order.
I did both cleanses, and I liked Oxypowder more than Colonix, for many reasons. But mainly, I felt better during & after the Cleanse, then when I did after Colonix. But you can't go wrong with either one.
Keep us updated on how the Liver Gallbladder Cleanse goes, because I'm thinking about doing one next.
