Not sure if they are selling duds in the name of genuine products. I bought some Horny Goat weed which is known to be a really strong aphrodisiac but it literally had no effect on me. And this isn’t just one dose. I have been using it since the past 2 weeks as prescribed; and there hasn’t been any improvement in my sexual activities. For the first time in my life, I am regretting the decision of having bought something online.
