Grail,
More thoughts.
The reason guys have been wanting to try Progesterone creams etc is to boost its 5AR metabolite, Allopregnanolone, which can be depleted during Finasteride usage (see the studies in “Finasteride Studies” section for confirmation of this).
However, there are some other Progesterone studies posted in the “Other Studies” section, that show Progesterone can inhibit libido, lower T and surpress LH/FSH…
In addition, I have read that Progesterone also inhibits the actions of 5AR (thus inhibiting not only DHT but also 5AR Progesterone --> Allopregnanolone conversion – which is the whole point why some people are taking it in the first place!)
My personal opinion would be: get blood tests for Allopregnanolone (and potentially GABAA) first, then determine what can be done from that point forward if its out of range.
Most likely I would expect people’s Progesterone/Allopregnanolone/GABAA levels to return to normal after Finasteride, but you never know.
Just my thoughts…
