By far, Prolab's Horny Goat Weed
ProLab Horny Goat Weed - IllPumpYouUp.com
It made me a horn-dog, and gave me ball-tingly winglys. I could tell it was working. My "hardness" was way up, which is also a "big" sign it was doing its job.
I've tried several over the years, but this worked the best for me. Plus, it's so cheap for all you get. You could run it, and another test booster and get more bang for your buck.
