As i was reading up some articles online on the effects of Viagra, I really got curious in a way since I am also a medical student and though I know that these erectile dysfunction medications are specific in their actions and works only for impotent men, I cant help think otherwise what they can do for normal men. So I made a little experiment on myself and bought some Online Viagra to test. That same night I got the order of Viagra, I drank it, got ready for some bed action with my girlfriend and I even asked her to notice if anything might be different in my performance for that night. Well it actually turned out to be a failed experiment as there were really no significant change in me that time and so I figured out really these were just built for erectile dysfunction and so shall it stay so. Same goes for Cialis and Levitra as these are part of the big three of erectile dysfunction drugs and now I can say so to those who are aspiring to try this meds even though they have no impotency whatsoever, they are simply wasting their money as these medications, though potent for men with erectile dysfunction, happen to be useless when tried by normal men. And take it from a medical student who have tried it so and failed to elicit and positive effects of Viagra on normal men.
