Query: Amazon Removed My First Review. Caveat Emptor

For an unknown reason (to me) Amazon removed my review for this product, so I'm writting another review. I bought the cream, and I'm on the second jar, but I still don't know if it's working. The amount of progesterone is not listed on the product, and when I contacted the manufacturer, it claimed that it was proprietary info. This leads me to believe that there is less than 450 mg of progesterone in the product. I will be buying another brand that lists at least that amount on its label.
