Just wondering when you guys started to notice your voice changing? How far along on T were you? I know everyone is different but am just curious.

2 weeks when it began, still noticing small changes almost 5 years later

I noticed some definite changes within the first two weeks.

I guess I'm one of the slow guys. It started around 6-8 weeks and is still going on (I'm 5 months in)

I'm with Mr. X - mine didn't have noticeable changes until the 3rd month.  At month 5, I was getting "sir" on the phone.  It's not shifted too much since then, but I'm only 2 years in. 

I noticed it starting to change after 1 month. Maybe 1.5 months.

Judging by my voice clips it stayed the same up until 1 month. By 3 months it had dropped a lot compared to what I started with but it got all croaky and...squeaky almost and stayed that way until about 6 months in when it finally settled.
