for the most part doctors don’t know shit about trans healthcare (or are actively hostile), unless you get very lucky with your endocrinologist you really need to educate yourself so that you can tell when and how to take matters into your own hands (and be able to identify if your doctor is trying to fuck you over, intentionally or not)

for this reason a lot of trans people just cut out the doctor entirely and go full DIY, buying graymarket hormones online (which also have some advantages over the legitimately available products in most countries) and tracking their hormone levels themselves

EDIT: see this other comment i made like an hour ago for an example
