Horny Goat Weed has been used for centuries in a number of different cultures as libido enhancers, aphrodisiacs, and to increase arousal.
I would like to start by saying that my partner and I have no problems in the bedroom, but we received a complementary bottle of this product to try, in exchange for our honest opinion. So if you are looking for help with actual problems in the bedroom, I can't speak to that. (Also, I would advise you to speak to your doctor first. You can always talk to them about using natural supplements like this!)
My partner and I decided to try this, mostly for fun - who doesn't like to spice things up a little, now and then? :) It definitely had an aphrodisiac effect for both of us. We have tried a number of different libido enhancers (because we review quite a few products), and I find that the ones with a combination of horny goatweed and maca root have more of an effect than just the horny goat weed.
