Highlighted Reviews

— Dez

"I've been using this product for the past 4 years and I always keep a bottle in the refrigerator just in case. It's the only product that works as the bacteria is kept cold in a dormant state until needed."

— Rita

"Don't understand how it can work for some and not for others. It absolutely did not work."
