My endocrinologist , who is part of a major university gender clinic , supports the use of progesterone . his recommendations are to take estrogen for 3 6 months , then he does an evaluation of breast tissue growth , and then adds progesterone for the next six months . He said it helps with overall breast development as well as enhance the development of the milk glands . AND , it ' s worked GREAT for me . I personally would do it DIY if the doc did not prescribe it . but that ' s just me . good luck young lady ! ~ Joelle <| sep |> OH Thank God , I am not alone . I search YouTube every day for vids .
