You know what, I’ve thought about this too. I’ve known fin is a super common drug for transgender people too and I guess I have felt strange that more of them don’t get the worst side effects (anhedonia, memory impairment, etc.)
I will say though anecdotally that I’ve seen one post on Twitter from an MtF person say she was dealing with brain fog from one of the drugs (I forgot if it was Fin but I think it may have been, or at least something similar) and that she doesn’t like taking it because of it. So that’s at least one example.
But still, you would think it would be far more common. It’s interesting to say the least.
