I was under the impression that in the U.S., estradiol is most commonly prescribed. That's what I got, plus spiro, right away.
I'm not sure what you mean by "look like a freak," but I noticed some changed within about a month, though nothing that prevents me from presenting male. I'm getting to the point at three months that I might not want to go topless, and might soon need to start wearing a sprots bra while in guy mode, depending on my shirt, but I'm pretty sure I could go on presenting male indefinitely. But there are subtle changes that help with my female presentation.
