did a little digging and found something horrifying
I found a person called "Lena Kiev" (probably a pseudonym), selling homemade estrogen solution for MtF people in the USA since 2006, selling worldwide since 2017. You don't need a prescription or anything, and the website is operating on the clearnet. This person was mentioned often in trans lefty circles on twitter, which could mean hundreds of people are injecting themselves with homemade estrogen, potentially thousands since 2006. "But getting estrogen is difficult and trans grooming doesn't exist" Lol.
