Met Rx protein plus power whey shot

Hi All,
I was wondering if anyone has had a rash after using this product.  I had it before and no reaction.  Any thoughts?  I purchased these from Sam's club and they are at tolerable, but the rash and itching is driving me nuts tonight.

Thanks for any insight.  I also posted on the DS site.  Maybe someone has any idea as to why?
