For me the first changes was hair around my body but that depends on genetics, tho most things with T do. I started on a low dose as well and on patches so my voice started changing but not to extremes until I started doing injections now my voice matches my age more and I'm a lot happier with it, but I was happy with the changes back then too because it was progress. It started changing my hairline, added to it surprisingly it made kind of a widows peak. a lot of people talk about bottom growth immediately after starting but I didn't really experience that. and one of the biggest things was I felt a lot more stable and rational. I have mental health issues but it's definitely helped a lot with being overly sensitive or emotional to smaller things
