I'm looking into starting DIY, I really just can't wait any longer. However, I am absolutely terrified of needles. I won't be able to shoot myself up with it. I'm looking into the forms of estrogen, and it appears that I can buy the form used for estradiol pills. But I'm finding very little information on DIY that isn't focused on injections. I'm thinking about making a water solution and just taking it out of a dropper, but I know I'd need a preservative to keep it safe for a long time.
This website helped me out tremendously back when I was looking to get started on diy hrt: https://diyhrt.wiki/transfem. It has a lot of good info on transfem hrt, including the two main types of oral intake (swallowing and sublingual).
Don't really know anything about using a dropper, but I remember that the homebrewer TeaHRT sells something like that: https://teahrt.com/product/sublingual-estradiol-oil-dropper-30ml-20mg-ml/. They currently only ship inside , however.
