at 3-4 months you should be beginning to pass but everyone is different. at 3 months, my voice dropped but again, everyone is different. as for the weight..well, i started T when i was overweight. i was on a higher dose and when i lost the weight, my doctor put me on a lower dose because my T levels were too high. i don't know if my changes, etc. would have been different though. i've heard that being overweight makes your changes slower though. if you already have a belly, your body fat will shift to a more "male" pattern. you might slim down tbh but if you do gain any more weight, it will go to your belly and your current weight will probably shift to your belly too (mine did). just eat healthy and exercise. when you go on T, your hunger might spike so you will definitely want to watch your weight more.
