Feminizing HRT is actually useless

HRT is extremely potent for anyone pre puberty. But even middle or post puberty estrogen is useless whereas testosterone has many uses.

Testosterone can drop your voice and grow you body/face hair.

Estrogen can't change voice, it can't change facial hair. It can give you fat growths so small that don't deserve to be called breasts. That's it.

After puberty testosterone has an effect whereas estrogen does nothing.
