question about testosterone and singing range?

im a trans guy and i plan on going on testosterone later this year, but my main hobby is singing. i dont do lesson or any professional stuff but im in a band and i get a lot of enjoyment out of it i also enjoy musical theatre and opera songs as a hobby.

my main worry is that after i start t ill lose most of my range (soprano 1 my range is a3 - e6 ? maybe? i think i can go higher than that) please someone tell me ill just become a tenor if i practice while im on t. PLEASE SAY I WONT BECOME A BARITONE IF I JUST PRACTICE ENOUGH
