Which color maca is it, to raise L-dopa levels?

Seem that I made a mistake, Mucuana pruriens is what I need to take for L-dopa. Does any body know the proper way of taking it?
I read this on a supplement forum:

“Synthetic L-DOPA used to treat Parkinson’s Disease is called levodopa (L-3,4-dihydroxyphenylalanine).
L-DOPA is (L-3,4-dihydroxyphenylalanine). The main extract used for ALL L-DOPA is MP/Velvet Bean.
Do you understand this relation? L-DOPA has been shown to release high amounts of Dopamine, and Seratonin.
This release over a long period of time care wear on these receptors. The MAIN chemcial in PowerFULL is L-DOPA.
You previously stated that L-DOPA releases " 200-500% AUC " I do not refute this. However L-DOPA is known more for its ability to release Dopamine, and Seratonin. MP/Velvet Bean extract IS L-DOPA. L-DOPA taken for long periods as reccomended with PowerFULL, without a DOPA decarboxylase inhibitor (DDCI) is harmful to the natural stores of seratonin, and dopamine”.

What is a Dopa decarboxylase inhibitor?

I also read that you should take 5-htp ( serotonin precursor ) if taking L-dopa.
Someone stated you should take 50-100 mg 5-htp along with 300-400 Mucuna ( l-dopa).

I am a bit confused by all this…anybody have experience or knowlege in regards to supplementing with Mucuna Pruriens?

Anyone try mucuna?
