I believe this is a drug we tried off-label a few years ago: no effect. To be fair, perhaps you have to take it for a long time, and as BB99 noticed, you have to be drug free (meaning very early in the game) and I am pretty sure we were already taking sinemet when we tried it (with the approval/blessing of a very well known PD doc, I might add).

Hope it works for the newbies
