Estradiol (bioidentical) does this as well, it’s not a limitation of just premarin. I have two cones so I would know! You need progesterone generally to get rounder boobs (it promotes the growth of the milk ducts, E just promotes growth of the breast tissue itself).
Now also, as a disclaimer, what I just said about cones and prog is partially anecdotal; prog hasn’t been studied all that much yet, but quite a few transfems report cone boobs until they start prog (I will be starting it within a few months <3).
