5 year experience.
Reaching that 5 year mark for pfs. Tried a lot of stuff. Clomid damaged my eyes. PEA and Fish oil help the most. If I had to guess it's a gaba signaling issue. Increase gaba signaling at all costs. Eventually allopregnanolone may come back. I take magnolia extract too.
Edit: I did some more research because of this post. While I do feel better taking pea it probably doesn't work for everyone who is totally crushed. Fish oil is ok but does block 5 alpha in peripheral tissue.(Not sure about this either, Ive gotten bad with research).And magnolia does have a bad effect for 5 alpha type 1 in the brain. So do research and see what's best. Grass fed butter might be better than fish oil. And valerian better than magnolia. As for increasing gaba I would just take a pharmaceutical to avoid this stuff.
