Fuggles, I just checked the website again. It doesn't say how long the cleanse takes, but it is 240 capsules plus 50 ml liquid, so it is probably not 8 days, but 30 days(at 30 days that would be 8 capsules a day plus the liquid. If it was just 8 days, that would be 30 capsules a day, plus the liquid(I doubt any cleans would use that many).
