AH one of those. Hmm and also from what I recall (been a WHILE) but the dione versions of many of the PH's were well lets say not to greatest and really more sides than any positives.
Yup as I thought the dione version can and does convert directly to estrogen. here is a little tid bit out of my old research I dug up right quick.
the others I relooked up as well all point to using the Diol version as well.
So IMO have a anti e on hand and at best you may get something out of it. At worst its all convert to estrogen and the anti e you have will block it.
