You may remain sceptical and not try it then. Entirely up to you.
But I do take issue with the article you post which says transdermal does not work. I can 100% tell you that, for me, I absorb well via cream. I am under a bhrt clinic who specialise in such things and deal with thousands of woman using transdermal products, including progesterone.
Now, there are probably differences in the products from different brands.
There was quite a bit of chat some time ago on the alternatives section.
In the US and Europe, transdermal progesterone is much more common. In the UK we seem to have a fear of it and certainly an attitude of it doesn't work.
Well, I certainly absorb progesterone through it.
You can make your own decision.
