Been on it a few months. I got immediate changes of all kinds, but I suspect part of that was my natural T and E levels being abnormally low anyway before I got my script, there was very little E in the system to counter any effects of a low-medium T dose.
Being on T is great. I feel healthy for once, stronger and able to take more physical punishment, and low hormones are a nightmare psychologically so with that dealt with I no longer feel like a 1000 mph emotional and physical wreck. Adjusted to the body hair, sleep, skin oil, sex drive, and all that. Happy with what it's doing. Probably going to take a while for the facial hair but the voice is pretty low already and it's great to hear myself sound like I do.
My voice went hoarse within the first 5 days and by the end of the first month the tone was noticeably deeper. I started in October so it's been a while. Seemed to drop in stages, first month, third and fourth. Third especially. It still has further to go in my view, at least I'd like it to, I don't know at what point the cords stop thickening on T though.
