Go to a doctor for a prescription and supervision.
There is estradiol valerate. One form of hrt with injections or implants drives the levels of e well into the female range, sufficiently to drive t down into the female range without further anti androgen. You might talk with your doc about adding bioidentical progesterone (not synthetic ones), many say it helps with breast development, has some antiandrogen effects, might help with mood and counter some side effects of estro.
Just talk it all through with your doc.
