geoboy,
The Cialis that people are taking has the exact same ingrediants as the Eli Lilly brand. Of course just like anything, things vary. However, the Cialis that has been around for a while in the USA, is working just like it is supposed to, with the same exact side effects that Lilly posts.
I have had both the European and the Other, and IMO they worked the same. The Cialis I am talking about is made in a lab, not in a home. Peace
