Hi Gerry,

Interesting. My homocysteine level is normal too, but I have one of the CBS mutations so apparently the CBS is upregulated, so I dump glutathione (dopamine) through the CBS gate too fast. One thing that was fascinating about the Hinz testing was that I had tons of dopamine in my urine so why is it not in the brain where it's needed? Maybe my always open CBS gate explains that. So I've lowered my intake of sulfur to close the CBS gate. Maybe that will help.
