Haha I think you have misunderstood!
I was soprano...
Then I went on testosterone. Testosterone treatment makes your voice develop the way a man's voice does during puberty. What I ended up with is a voice that is naturally in the baritone range (Sometimes I wonder if I'd be a bass by now if I hadn't quit testosterone when I did...). I cannot ever do soprano again... well, unless I practice really hard to open up my full range and control such high notes. But that would require years of practice and bottom line still remains: baritone is my natural vocal type now.
High notes are my main difficulty actually xD
My comfortable/good notes are G2-A3 after a bit of warmup, with an additional slightly weaker F2 and an acceptable B3, however that B3 is kind of the note that's edging on the "needs work" part of my range. I am starting to waver into an E2 as well it seems, hopefully a teacher can help me grab that note too.
I can go higher than that of course, but as I said it needs some work. I'm more interested in learning to go lower if possible tho because it's just a lot more comfortable for me to actually use, and more useful for the type of music I wish to produce. Goths like their basses, baritones and sopranos!
I cannot say specifically where I was as a soprano however I did have a whistle register that I was working on before I stopped going to a singing teacher. I think I was able to go above a C6.
Since it's just a matter of training again, I say it's no loss really since my voice gave me such awful dysphoria. Only thing I miss from my soprano years is my cat's reaction to the higher part of my register when sung with a more intense vibrato. He would like purr and shake his head
Now he only purrs and occasionally meows back when I sing to him.
