*If you take low dose long enough, you will experience the changes that someone on full dose experiences.
*Chase went back to full dose and looks very different
*If you stop T, your face will go back to it's original shape and form. Your body will go back to it's old shape. what will remain is your lower voice, any male patterned baldness or hair loss you have, your clitoral growth, and depending upon how long you were on T, you will still have facial growth. However, it will be more soft and you will have to shave less.
*It took me 20 years to decide to go on T. I thought about it from age 25 to age 45. What kept me from doing it was knowing that once the voice is dropped, the voice is dropped. I didn't want to try to live as a female with a male voice. I started on low dose (very, very low dose...half of a half dose), and had a bit of a voice drop the first week. IF I had stopped at that point (or any point very soon after), I may have had a chance it would go back up. BUT, you should assume that it will not before taking T. By the third week, I had some significant clitoris growth.
*You can't pick and choose how you will look. Don't make assumptions about how you would look based on relatives. I would suggest not starting T unless you are willing to go the "whole way". I would say that if you can tolerate the gender dysphoria, don't take T until you are certain (or at least as certain as you think you will ever be).
*The day that I decided to take T was the day that I was sitting in a bar. There was a guy across the bar from me. This may be horrible to say, but I found him to be quite unattractive. He looked nothing like I would want to look (as a guy, or otherwise). Bad hair loss, facial structure not what I would want, body that was less pleasing me to what I even had at the time (I have always had a masculine build and he did not). I liked how I looked at the time (especially because I had already had top surgery), much better than how he looked. I asked myself this question. "Would I rather look like this guy in order to live as male or would I rather continue to live as a masculine attractive female?" The answer was I would have accepted looking like him, in order to live as male.
The point is, you need to get at least close to a place where you are willing to accept what T will give you, even before starting low dose T.
Good luck to you.
