There is no way they aren't just straight up going to come for us.
Edit:For Cis comrades, spread the word and emphasize the seriousness of this to everyone you can. Making sure people actually know about this is the most important thing as the majority of people just dont know anything or pay attention.
pressure cooker probably doesn't help here because it's hard to control temperature and the seal means that the pressure arguably doesn't help neutralize contaminants. luckily, I did research into this for the same reasons, and it turns out that estradiol can pretty safely taken up to 200C without damaging it, unlike testosterone. so at least for trans women, you can safely make hormones by getting a specialized oven for like $100 bucks that will keep the temperature at between 180C-200C for an hour. do make sure to do spore testing though - you need to intentionally contaminate a sample with resistant spores, put it through your process, and have a lab verify that they couldn't get the spores to grow.
I have notes on all this somewhere I've been meaning to post... let me dig them out and start a thread.

oh got it. people sometimes use a pressure cooker as a makeshift autoclave and I just meant that it won't work like that. I haven't actually tested this yet to see if the pressure build up in an oven causes problems.
