none of my doctors want to check my estradiol. ive talked to several, and none seem to think its important. but i know it is. i think the only way to get them to listen, is for me to try out an ai first and if it works (e.g., fixes my ED), then i know im off to a good start, and then ill feel more comfortable getting an outside blood lab to check my e2 levels so i can show them , "look, it is important." its worth a shot because im out of options! btw im on 200 test cyp a week.
