to add to the websites you listed, pghrt.diy is a linear guide to transfem hrt that is pretty easy to read imo. beware that it is very opinionated, but that can be good if you’re the type of person who can get easily overwhelmed with too much info like i am. it was invaluable to me starting hrt.
also, valerie.vg (formerly diyhrt.market) contains up-to-date info about what suppliers of transfem hrt are in stock, their prices, links to reviews of their stuff… when you’re ready to order, look here first to find who to buy from.
also, the tor browser. diy estrogen is not a crime in most places, but you’ve seen how the state treats us… so, act accordingly. many diy suppliers (and valerie.vg) have onion sites too, i recommend you use those, they’re way harder to shut down
finally, this comment has been very transfem-focused, because that’s who i am, and i don’t know much about transmasc diy hrt. if someone does, pleasepleaseplease reply here to share so we can better help our brothers & siblings out!
