I just restarted Atkins again a week ago and I have Ketone Stix by TestMedia left from when I did it this summer. There is no expiration date on them but when I test (I should be in ketosis) the strips don't change color but become dark gray. I don't see a hint of purple in them although I am not drinking very much water so if I was a bit dehydrated I wouldn't be surprised. But they just go from gray to dark gray and if I remember correctly it seemed that when I did it before they were more of a tan color (closer to the neutral color on the bottle). I am wondering if my strips are too old or what. I know the strips aren't the be all end all of Atkins but I would like some confirmation so have the encouragement to stick with it. Has anyone had this problem? I was considering having my 5 year old pee on it to get a non-Atkins sample! Please help.
thanks
