Yes, I've been using it along with tyrosine, glutamine, etc as a substitute for my low dose of Adderall for ADD.

My story is too long but you can read some of it in my hair test history #354 here.

I'd try tyrosine before mucuna puriens. You'll also want to get the the cofactors required to convert it to the various catecholamine neurotransmitters--Fe, Cu, Vit C, several Bs. Be careful of Fe & Cu if you don't really need them!
