Query: Not good if you have a reaction to them

These things are pure evil. Used them for a couple yrs no problems. Then they went and changed the formula and told no one. Thought I had a severe case of jock itch for over 6 months. Kept using these thinking the "leaner" the better. In one of my many 100's of google searches found out they are now using a different preservative that supposedly only effect a few people out of a hundred. Well god be with you if you choose to use this garbage. It took 3 months of not sing these things to get my bum back to a semi normal state. Beware guys. I have even read new stories about some post man who was laid up for months his reaction was so bad.
