you know Sas Palmetto works by
1-stopping type I and II every where
2-binds at androgent receptors in all kind of tissues.
Now so far all SP suffereres have one thing in common. They used SP liquid lipid form soft gel Caps. We know lipid form can easily cross blood brain barrier. I googled and found some SP berry powder users who got sides like Gyno or liver problem but as soon as they stopped they became normal. All they people who are stuck are those who used liquid form.
Now maybe find did the same thing and crossed our blood brain barrier and bound to receptors in our brain.
