I've been on a variety of HRT methods for the past 4.5 years. The majority of the time was spent on pills, and I also tried patches for a year or so. I've been post orchi for a few years now and switched to injections 3 weeks ago. Since switching to injections my breast growth, that has been stagnant for years, has taken off. If I could do it all over again I would have started with injections.
