I tried one pill that was a round orange tab. It worked ok, it wasn't amazing or anything, but I felt it for around 3 days or so. I gave one to my girlfriend and one to a friend and either one said they felt anything. Now I have some blue triangles that are supposed to be Cialis I'm going to sample and see what happens. I thought Viagra was a blue triangle? These are from the same guy as the round ones though. Guess I'll find out.
