I would say that the estrogen you are being recommended might be a bit too much. My approach would be to introduce a little of it, take blood tests, and tailor the hormones for your body. Your levels need to be right - the amount of hormones taken to get to that point is irrelevant. The Spiro looks more or less right... though the Vancouver group uses a higher maximum.
If you can't do tests, then you shouldn't self-medicate. Testing takes a lot of the danger out of it with a cautious approach... however, there is, of course, always the possibility that the medication that you're buying isn't actually Estrogen and Spironolactone.
I would find a safer and likely cheaper way to get the hormones myself, if I had to self-medicate.
