Deciding on the product

Hi, I have heard about your products from close friends and they sing your praises! I'm keen to try the herbal detox, but wondered if you sold two weeks' worth rather than a whole month? I'm just thinking about affordability here. Also, I am keen to lose just a couple of kilos. Do you think this is a likely outcome from doing the ultimate herbal detox or should I do the herbal slim instead? Thanks so much, Yvette
