/fit/bro here. I'm literally turning insane. In my shitty ass country they use the Free Androgen Index(FAI) to measure free testosterone in men. Now, the Endocrine Society says that it shouldn't be used when measuring Free Testosterone IN MEN, as well as every single study I've read so far says that it's a shit measurement for free T in men.
I'm not educated when it comes to this so I have a hard time trusting my own intuition. Is there any data that disagrees with this, any reason why the FAI should be applied to men? I feel like a fucking conspiracy theorist. My doctor just dismisses what I say without explaining why.
