Ron Hutton and I both tried it in various forms a couple of years ago. My own experience was positive and I plan to get back to it. In fact, just yesterday I bought one of those little trays for filling capsules with mucuna in mind...

I tried it as raw powder, a standardized form called "Dopabean" by Solaray, and a strong concentrate by Herbalife. They all worked much like Sinemet. You had to do a little trial and error to get the dosage right, however.

I will probably reintroduce it in a few weeks. The reason I quit the powder was that it is an incredible staining agent. Black as can be and it does not come off. That's why I got the capsules. I can fill them outdoors.

Mucuna is a far more complex substance than levadopa. One thing that particularly interests me is that I was using dosages roughly equivalent to the Sinemet and getting similar results. But mucuna has no carbidopa to shield it from your body's enzymes. According to conventional wisdom, almost none should get to the brain. Yet it does.
