I actually experienced fat redistribution quicker than I expected. I'm currently about 8 and a half months or so on T, and I've definitely noticed a more masculine body shape, particularly with how my fat sits on my hips/thighs vs waist. It was such a gradual change that I cannot tell you when it happened, and I wouldn't feel comfortable describing a 'peak' since I am only 8 months on. Also, something I didn't expect so much but I definiely have noticed is that I can feel a lot more of my bones. Not in a losing weight kind of way (I've gained actually) but its like there is less fat on my joints. Elbows particularly, but also on my wrists and fingers and now around my neck as well. I do not exercise, the most I get is walking between classes and climbing up my bed. (I'm the top bunk.) I will say I lost some fat from the top of my butt surprisingly early on, however, very little of my butt fat has redistributed compared to the rest of my body. My waist size has gone up, however my thighs/hips have slimmed down.
One thing I always struggled with was insecurity about my weight, and I could never tell whether it was a dysphoria thing (like how my weight is carried) or if it was a body image thing. I've realised now it's mostly a dysphoria thing because I am much less bothered by my weight now. Even though I weight abouto 20 lbs more than I used to and I have more belly fat, since it's being help in a more masculine way, I really don't care all that much. Sure I'd like to lose it, but I'm much more bothered by other things now.
