I started female puberty at 9 (cycles and chest development, the whole deal). I don't think it's had any effect on how quick T is working for me. I'm basically at 3 years (3 years on, one year off, now 3 months back on) and I had some changes but not very quickly. Of course, my dose was a bit off since I was doing my transition overseas from my doctor. I've heard it can take 5+ years on average to get the changes.
