I highly recommend that you go Here and read this thread on the Mind and Muscle forums about Catuaba.
The initial poster had experiences that were very similar to mine, although they were a bit more intense, probably due to the fact the he looks quite a bit younger than me. I can still take a leak without getting a hard on, fortunately.
One thing that really caught my eye were the messages from other people, who had given it a try, and hadn't experienced anything. Being experienced with this stuff, I know exactly why it didn't work for them, and should probably go back and enlighten them all when I get a chance.
The problem is, most of the stuff you buy on the net sucks. What I've found is you have to have the powdered bark, straight from the tree, and it needs to be very fresh, and strong smelling. The problem with most suppliers, including those discussed in the thread, is that their stuff is old, dry, and lacking in potency. The guy in the thread is a lucky man. He lives in Brazil, and obviously is taking the good stuff, fresh, and right off the tree.
Another problem is, there are several varieties of plant being sold as Catuaba that are not the real deal. What you need is Erythroxylum Catuaba. Unfortunately, quite often, product labeled Erythroxylum turns out to be a completely different species once it arrives in my mail box, and I have a chance to look it over.
My solution to the problem was to find a supplier, and import very fresh product directly from Brazil. The downside is, I have to buy a minimum of a kilo at a time. This problem has taken care of itself now, as I've got 7 of my friends and relatives following my protocol, so we're going through a kilo every few months or so.
The last time I ordered, I knew I was going to start blogging , so I purchased an extra kilo and have placed it on the net HERE for those interested. It's the fresh stuff, broken down into quarter pound packages, which should last you at least a couple of months. If it turns out not to be too big of a hassle, I'll continue to offer this service in the future.
Here is a page with some additional info on Catuaba if you'd like to read more.
