Ive only been on T 5 weeks but ill answer what I can..
How long before your voice started to change after first shot? Different for everyone. Mine has gone down slowly, still at 5 weeks not a HUGE difference, but i never had a girlish voice either.
When did you start to see increased body hair (leg, arms, etc.)? I saw leg hair within the first 2 weeks, arm hair.. nothing really yet, SOME light chest hair(nothing to brag about) and a little bit of a happy trail 5 weeks in..
When did your periods stop? I had one after my first shot, and it lasted longer the usual(weird??) but i might still get one later =[
Have you experienced a change in how you thought about something or become interested in something way outside your interest level? Not at all.
Has your sexual prefrence changed? Preference? No. But I have become a lot more interested in checking girls out.
Did you get a confidence boost, less disphoria? Not really, I was pretty confident prior to T, and my binder is the best help for disphoria.
When did you start to notice fat redistribution? None yet.
Did you experience weight gain or loss? If so how much? Weight gain? Yes, but im not sure if that has to do with T.
Have you gained some muscle definition and increased strength? Since starting T i've become much more interesting in weight lifting since results come alot faster with T, so im not sure if its because i work out more, but i have gained substantial muscle.
