Apple cider vinegar is also an aphrodisiac, men only it seems. I used to take two tablespoons a day mixed with juice, energized the heck out of me. After meals of course, don't want to take anything that acid on an empty stomach. Had some of my buddies taking it as well and they swore by it, until we discovered BaJi down in chinatown and then *that* ship sailed. ACV is a lot cheaper though and great for working out, maybe I'll start using it again in the fall.
