Looks like progesterone is at the level of wunderdrug that people are sending unsolicited DMs on how to get it in the UK.

Background: I replied to a friend's tweet about starting progesterone asking how she got it - out of curiosity, rather than a desire to follow her path.
I got an unsolicited DM from someone i dont know in any capacity detailing where to buy progesterone online and how to convince the gic to be okay with it.
