It looks like you have about a 50/50 chance, if you take about a gram, for it to work. It sounds like this product is a bit scam-ish. Plaster the words 'aphrodisiac' on it, put it in a gas station and there ya go. Not saying that's where you got it, but I see that shit all the time. I like to read the ingridients. Its fun.
