I will try to pull something up - I am not familiar at all with this part of the adrenals.
I will alert some other member to see if they know things.
if you're getting low in dopamine, a lot of folks try using the precursor nutrients, such as tyrosine, or phenylalanine DL. It's found in chicken, eggs, milk and cottage cheese.
Tyrosine converts into leva dopa, and you could try mucuna pruriens for that, but dosage is sketchy on each brand.
L-dopa is the last stop on the train before dopamine, cuz from what I understand, you can't "take dopamine". You give your body the nutrient and it has to make the stuff.
