On hormones, new fat is allocated to typically feminine areas. As you live and exercise, you lose weight in general, so fat gradually fades from typically masculine areas, and with the process of life it accumulates to the feminine areas, giving an illusion of distribution of existing fat.
Hormones won't just put your fat into feminine areas. It's biology. It will take time.
I'd also recommend you eat a healthy diet... 4000 calories a day is absolutely crazy. If you want to gain weight once you're on hormones, I'd suggest doing it slower than you are now... half a pound a day would be a lot better, though still rapid. I'm not a doctor or nutritionist, but this is what common sense would suggest.
I do envy your ability to gain weight, though. Perhaps 2000/day would still result in gain for you... and if that's the case, then you're lucky.
