I've been on T for about 3 and a half months now and I've noticed a decent drop in my voice. When I was pre-T I was able to lower it to a passing level with some vocal exercises but I wasn't expecting T to have an effect this soon and with the dose I'm on.
It used to be hard for me to listen to recordings of my own voice because it sounded nothing like me. Now I love how it's changing and I can't wait to see how much further it drops.
Pre-T and before any vocal exercises:
(Wait for it, wait for it...)
