@Hussle1738 i don't know how peaty this is, but maybe try picamilon (niacin and gaba bound together).
Gaba taken on its own is probably peaty and haidut has mentioned it does seem to cross the blood brain barrier.
Peat says increasing co2 will have a fantastic effect on gaba. He has mentioned valerian in a positive light with respect to this as well.
Progesterone and pregnenalone (from peat):
"Progesterone and pregnenolone and many other things act on the GABA receptor system. And pregnenolone happens to be one that doesn't have many other hormone-like effects. It's basically a stabilizer at all levels of cells in the brain."
Seems like just going harder into peating will naturally stabilize the gaba system and may rid your nervousness.
