Using Resveratrol in combination with Citrulline improves erectile function even in men taking PDE-5 inhibitors, as demonstrated in a recent clinical trial. Thus, Alpha Male Plus is designed to benefit all men, including those who already utilize PDE-5 inhibitors yet are nonetheless seeking more power in the bedroom. Alpha Male Plus is the only men’s sexual health supplement that contains the correct ratio of Resveratrol and Citrulline to leverage these exciting clinical insights.
