Topical Progesterone?

Hey everybody.
I’m just curious and going to put this out there: Has anybody tried topical Progesterone as either a growth or tissue repair aid?

I stumbled across someone mentioning “wearable progesterone-containing devices” having been experimented with for promoting the regrowth of limbs (…in frogs…, in the “Banding my Penis” thread), and after reading more about it as a precursor to either testosterone or as an estrogen suppressant, I’m wondering what relationship it might have with smooth muscle growth, particularly locally.
Anybody in the relevant medical community know anything about how a topical progesterone could or could not relate to tissue proliferation? Has anybody experimented with it? Searching the forums hasn’t really yielded much discussion on progesterone specifically.
