A mate of mine tried it , it was prescribed to his brother who gave him 1 pill. He reports that it didn't make him feel more "horny" but it did have the rather unfortunate side effect of giving him inappropriate erections for example, when putting his hand in his pocket to get loose change or, as he reported, just after urination whilst atempting to stow "Percy" away. Seems the sometime unwelcome side effects can last for up to 3 hours. I just don't get why any erection acan ever be "inappropriate" myself.
