I purchased this garbage service to see what’s going on with my health. I can assure you that you will pay for the service - you will go to quest. Quest will not see your order set. After you find out quest didn’t get your order set and that the confirmation code they gave you is invalid - you’ll then find out THEY HAVE ZERO COSTUMER SERVICE. I waited at quest for hours trying to resolve this just to watch quest close. DO YOURSELF A FAVOR AND CHOSE A DIFFERENT SERVICE. if you look at the reviews on trust pilot most of these reviews are internal and not authentic. AWFUL SERVICE

This is my second year w Function I learned so much about myself in the first year; I was celiac, my vitamin d was down as well as my hormones I knew I needed to do it a second year. It has not disappointed me.
