Query: Be aware if you are hypersensitive

The first time I took this was last night - and I broke out in hives all over my body.Being hypersensitive in general, I knew what it was.I have recovered, and will stick with the other brand of Relora I brought previously because I know I won't get an allergic reaction to it.(The other brand by Now Foods sold by American Sports Nutrition)
