doesn't this MD have patients you can talk to that are successfully benefitting from the hinz treatment? if you can't meet and talk to other pd'ers getting relief from this treatment that would be a red flag to me. the hinz protocol isn't cheap, the few users on this board recently complained about price increases if i remember correctly.

there are lots of treatment options between only carbidopa/levodopa and a very expensive, non-independently verified amino acid treatment. how much C/L is he presently taking and what else has he tried? i can't imagine any neurologist just trying C/L when someone is immobile.
