Thanks for replying. I was more concerned with the side effects and becoming dependent on this rather than the cost. I have not tried any of these before and read the side effects of blurred vision and others. I guess I will try smaller dose and take it from there. After crossing 50 I am noticing the errection is reduced and even more for the second shot. I missed out on a sexy girl in 20s amd could not get strong enough errection the second time.
