since dopamine can't pass the BBB, it sure isn't leaking out of the brain and i kind of doubt dopamine precursors are actively transported out of the brain thru the BBB to be used by the adrenals. just my guess.

As you say, dopamine can't pass out by the BBB. So we have a closed system and have only the dopamine that we make. `The adrenals are presumably on the periphery so they must make a second supply of dopamine? Something still doesn't seem right....
