As someone who legitimately is transgender and currently on testosterone, that is not at all how my experience was. They absolutely need to do blood work in order to figure out the correct dosages to give you

It depends on the doctor or what they are prescribing.  If you go to a "normal" doctor and just say I want to be on HRT, they might see if you need it b4 they give you a prescription.  If you go to a (example) "Sports" doctor and tell them you want on HRT, they will go through the motions but you will be getting your prescription.
