I don't have any experience with Horny Goat Weed (or rather, my fiance doesn't), so I can't give an opinion on that. But Yohimbe works better for us than L-Arginine, and GNC has that as well. But everyone's different, so what works for us of course isn't always going to be the best for everyone else.

Bindicat......Does it take a while of using the L-Arginine to see results or is it like Viagra & effects are almost immediate? My results from the generic Viagra are great-Can get hard as a rock in about 20 minutes, take care of the wifes needs & within 20 minutes or so I can be strokin' my hard cock again while checking out the pics around here-yours included by the way! ;)

It's fairly quick, you'd notice it the first time you used it. But it's not 20 minutes quick. It took about an hour or two before we were getting any sort of result (it was quicker for my fiance than it was for me).

I've never used any supplements before. Does any of it really work?

I'm still waiting for someone to come up with a pill that shrinks a woman's vagina.

Kegels will do that. And there's some stuff called Liquid Virgin that supposedly does that, too, but I've never used it so I have no idea if it works.

Just my luck! I sometimes get Shingles (on my knee only, so far); and L-Arginine is implicated as a possible trigger (L-Arginine is abundant in chocolate and peanut butter). So I take L-Lysine, which supposedly counteracts the effects of L-Arginine. But that's ok with me. If you've ever had Shingles (even just on your knee), you'll gladly sacrifice getting a bigger dick with a firmer erection to try and minimize the Shingles.

I sat out on an experiment and tried 6 diffrent enlargement products over a 3 month period with no results. It was worth trying they all had 30 day guarentees so it only cost like 30 bucks for shipping and now I know they dont work. I would assume none of them do after that. Horny goat weed does work about like Viagra for me. It gets me super hard and last quite a while.

Never tried horny goat weed but did take L-Arginine before (but not for libido purposes). I'll have to try it again and see if there's a difference. Oh yeah, and the only thing that works for increasing size is dedicated PE--no quick fixes.
