Galaxy, have you spoken to your endo about this? What are your levels like and what delivery method are you using? During my first go at transition, when I was only 24-25, I had pretty much zero boob growth after 24 months on HRT, to say it was disappointing would be an understatement, so I understand how you feel about the lack of development. Things have been much better this time around. Different endo, different 'mones, different delivery, different diet, older... different story. I did raise the matter with my endo but he couldn't really say if any of those factors made a difference, so I don't know, especially since I no longer have access to those earlier medical records to compare notes. Anyway, I hope you do get some growth, I know it feels very unfair to have the boob fairy seemingly ignore you.
