According to several studies I've read and doctors I've talked to, certain anti-androgens that only work by affecting T's ability to bind to its receptor site have a weak neurological effect (I believe this includes flutamide/bicalutamide) . I'm curious if this is because these cannot go past the blood-brain barrier.
The reason I'm interested is because I've had fairly low energy, slept longer, & been less active since going on Spiro. In the past, I've tried only taking E with no Spiro, and my energy & activity levels increased pretty significantly. Of course, though, that's not a long-term solution.
