After the second spell of EV being in short supply, I went back to pills and have been back on them for 2 1/2 years now. I don’t know where the misconception that injections get better results came from but I bought into it. The truth is, if hormone levels are in the female range then your body will respond according to its unique genetic code, nothing more.

The goal of HRT is feminization of a male body, primarily breast growth. If there was a delivery method or a hormone cocktail that was proven to be more effective in growing breast, then ciswomen would be using it too. And, their bodies seemingly would respond better because the effects of testosterone would not be present. The vast majority of breast augmentations are on ciswomen, not transwomen.
I watched an interesting presentation by Dr. Will Powers. His intended audience was medical providers, so I didn’t understand it all. He goes into detail why some trans women get a spurt in breast development when switching to injections, and said it has to do with conversion of estradiol to estrone and competition for E receptors. I think. He also refuses to use anti-androgens, and suppresses T through E. He has around 1500 trans patients. There’s also a pretty technical subreddit about him.
