Hello friends, I have been on hrt for 6 months. I am 20 year old. But not seeing much results. I take 4mg e and 100 mg Spiro a day by splitting 2 mg e and 50 mg Spiro at morning and night. So I actually want to switch to injection but I am going through some problems in life and some personal and family issues. So I don't have any money. Last week I got some money and I am thinking about doing blood test to check estrogen and testosterone levels. If possible I will also switch to injection because it is cheaper than pills here and I can do monotherapy. So which blood test I need to do. For testosterone I know I need to check total testosterone but what about estrogen. I don't have any prescription. I am doing hrt by myself. So which test I need to do for checking estrogen levels.
