I've not really known anyone in the U.K who has had implants, most people get okay results from patches although as you have pointed out, I think that the U.K is a bit lacking if you are TS and I have already pretty much ruled out surgery here, I'm just going to see how I get on with patches and from what I can gather, Dr Curtis does at least care about the amount of feminisation that occurs. I think that there are places where you can get injectable E over the net, but whether it's reputable or whether it will be picked up by customs is another matter.
