There are no ideal levels. There is no scientific evidence on which to base ourselves to say a certain range is ideal for all transwomen. Ask any doctor to provide the evidence, they won't be able. It's arbitrary. Range in ciswomen is 15-650 pg/ml during menstrual cycle, up to 75,000 pg/ml during pregnancy so whatever level you end up with, you are in range. lol. Doctors disagree on what levels are ideal. One needs to also take into account that not everyone is the same, it's called sensitivity, genetic factors, etc so that some need more, some less.
Levels measured are also taken at a random point in time and most likely, they fluctuate so they aren't reliable. My levels decreased by 1,000 pg/ml in a couple of days on injections!
T range is usually between 15-90 ng/dl (0.5 - 3.1 nmol/L). Some women feel better on more, some need less T to feminize well, it depends. My total T is 0.3.
The important thing is you're healthy, feel good and are feminizing.
