What are some of the ingredients to look for?
For instance, Yohimbe is great because it has been used for ages in certain regions of Africa to increase blood flow to the penis, which is important for achieving a stronger, longer-lasting erection. You also want to see Tribulus Terrestris, which has been shown to increase testosterone levels. A product called Vaso Prophin is marketed as an effective formula for men, but I don't see any of these ingredients, nor do I see other leading male sexual enhancers.
