I've been in all four of these companies. I'm still in ACN & I'm not to fond of it but my sister is making good money in it and has an incredible upline. Genewize on the otherhand is incredible. I joined for two reasons. What it is and the money opportunity I saw. I have been taking it for about three months. I physically and mentally feel better then I ever have. My dad has had an incredible turn around because of this product. I can't ever remember how the money works when I'm telling someone about it, because I'm always wrapped up in my testimony or someone like my dads testimony. It's crazy!!! If anyone has positive or negative things to say about Genewize and/or ACN I would love to hear it.
