First up was the Vaso Ultra. I found this and the other 3 brands to try online. This stuff is endorsed by porn star Ron Jeremy. I chose Vaso Ultra because it is supposed to contain a significant amount of tribulus terrestris. Apparently it's supposed to contain a proprietary type of tribulus terrestris called "Protodex."

I took two of these after dinner last night and then put on some porn. It did seem to help a bit. I was able to get hard, but I didn't think I was any harder or bigger than I was before, like they promised. I wonder if I should have taken some more to make it more powerful. Overall, I'd rate it a 6 out of 10. I would probably try it again if I had nothing else, but I'm going to keep looking.

I tried them all. Here’s the best one I found.. >> See It Now
