It seems parts of Melbourne are pretty conservative in treatment modalities at this point in time. I live in Sydney, and I'm a non-transitioner at this point in time due to various factors which I won't go into in this thread.
In any case, I'm on low dose HRT and my prescribing endo is comfortable with what we're doing. My endo is aware that I don't intend to transition at this point in time. If I'm not mistaken, RLE for a year prior to HRT may still be the practice in some parts of the UK under the NHS scheme.
Mikidiki, as you're in Australia, my honest opinion is that there really shouldn't be any reason why you're not under full medical care for your treatment. There's sufficient medical safety net (thank the budget black hole that is Medicare) that you should be able to access the professional help that you need. Other Aussie members of this forum have already mentioned the risks of going it alone, and although I like to DIY, this sort of thing isn't worth the risk in light of what you can get access to IMHO.
A final aside, if what's happening to your libido when your on an anti-androgen is upsetting to you, that can be a sign that full transition may not be the best thing for you. I hope that you're getting some form of therapy to sort out your feelings before you get too far along.
I hope I didn't sound mean, but I do like to see people do the best that they can for their health.
