Just so you know, macuna won’t do anything for mood unless it’s taken with a dopa-decarboxylase inhibitor. Dopa-decarboxylase is an enzyme that quickly converts L-dopa to dopamine in the periphery. Dopamine can’t penetrate the blood-brain barrier, but L-dopa can. That’s why Parkinson’s disease patients take the dopa-decarboxylase inhibitor carbidopa with their L-dopa medication.

Sorry to burst your bubble, but anybody shilling macuna alone is just using marketing to take money from naive people.
