For me the only thing that was almost instantaneous was my mood, overwhelming emotions, sometimes resulting in happy tears moments after being injected with it, good stuff, but everything else, very slow process. Either my dosages weren't good enough for me all these years, or I needed some extra oomph added to it, or well my body is just slow at growing, this includes these feminine changes. Okay, so I look fine enough now, but it wasn't an overnight thing, nor a few months, it took years. I love the physical changes, though always want for better results but there are some things that can't be changed just with hormones, but how it affects me inside is even more important. I had a really good day yesterday, but then later suddenly started crying, and this is how it went most of the night up to a little while ago, tears even streaming down my face while working out, didn't help that I looked at myself in the mirror earlier and didn't like how my body looked. So yeah, don't expect miracles, only that if being a woman is who you are, the hormones will make you feel right inside (I'm not on them at the moment, temporary set back), everything else just takes time and some occasional assistance.
