great question , about how I decided I read Mary53 a member here who is a nurse, she has an excellent page on hrt, I choose to try the least amt possible at first some women need testosterone. I did not. I did need
estrogen...I use Vivelle
patch for the ease of use, and accuracy in dosage, some hrt is cremes or sprays dont see how one would be sure of dose, the patch is very small about 1/2 square inch just apply 2 times per week( 3 for some) and thats it....
