Anyone here have any experience with deprenyl (selegiline hcl) ??? I have read some good things about it and am considering taking it at a low dose(1mg/ed) as a preventative and general mental enhancement. I tend to be all over the place in terms of focus not to mention that my father has Parkinson's so I am interested in protecting my own dopamine function for later in life. Is 24 too young to start a regimen of this type?
