trans | Researching testosterone blockers...

I've been thinking about testosterone blockers and I want to research more about them and their effects, both positive and negative before I take any more steps. I like to know what I'm asking for when I go talk to my health care professionals. :) I'm not interested in estrogen or other female hormones, rather I am exploring my options for where I want to go.

If anyone has any pointers to information, that would be greatly appreciated.

Thanks!
