depends on medications and your doctor. seeing a therpist at low income clinic will be around 180-300 a visit - whatever sliding scale fee they put you on.
then as far as meds go. depends greatly, oral name brand estrace goes for about $25 USD depending on insurence, around 4-10 dollars.
patches? $80-120 USD depending on insurence 40-80 dollars.
injectables, no clue.
edit: keep in mind this is the going rates from my neck of the woods in upper michigan
