Hey, my boyrfriend has had some of these Herbalife products dusting away for like a year now in his cupboard. Dust is still caked on a little. Ugh, he so doesn’t know how to clean. But, he didn’t know if they were still good since his brother is now trying to get him into working out and going on a special diet to help lose some holiday weight. I am so excited for him since I want my baby to be healthy. I will probably join him on the diet front, but I was wondering if anyone knows if Herbalife expires?
