Your'e right. Cross gender hormone therapy isn't rocket science, and those of us eyes deep in it may very well have better specific knowledge than the average practicioner. I can even applaud your informed approach, with enough research and effort you can probably devise a regimen that is safer and more effective than what a gp could off the cuff...or you could blow your liver out and have a stroke. You know this dear, you found out about your own clotting issue and have been taking care of it.
Where's the harm in taking a round of blood tests to a trans-friendly physician and getting their input? It might seem wasteful but who knows? They have a broader view of the body that we can't really get from individual research, and while I agree with you that just being passive and doing what they say without question is foolhardy, you have to admit their experience could come in handy as well.
