I know what he said and I know what he meant but he is wrong. Hormones made from horse urine are not exactly like the ones I made in my body. If they had been, my body would have accepted them, and it did not.
Some peoples bodies are more fussy than others.
What synthetic hormones did you end up on? Or did you just give up on hormone therapy?
My wife went (still is) going through that stage, but the doc refuses to give her hormones to ease her symptoms.
