Moonspenders: ok, I tried the free sample they advertized.. couldn't resist. i've been on it for over 3 weeks now. Honestly, maybe just mentally, I feel a little thicker (well, maybe 1/4 inch! LOL), but overall wasn't too impressed. i do recommend that you cancel right away if you sign up.. they bill you US$69.95/3 mos. if you don't (yeah, they suckered me.. no refunds available either, the bastards.)
The main ingredient, suffragium asotas, is a testosterone booster. So, it will make you hornier (don't be like me and be single on the stuff.. unless you want to fuck and suck everything in sight and have no one readily available!), and boost the level of testosterone running through your veins, but honestly, go to any online supplement store and you can get the stuff for about US$12.00/bottle. Much more cost-effective and easier on your wallet, but just as effective. The other stuff (Yohimbe, Kava-Kava, etc.) that's in it, you can get almost anywhere nowadays for cheap too.
