Caber did nothing, which was quite disappointing given the stuff you hear about it online, with guys raving about it turning them into porn stars. But Cialis definitely fixed my ED. I was never impotent though, just to be clear. Things were just more inconsistent than they were previously. But what Cialis didn't do though was bring my libido back. It's still in the tank. I haven't had any blood work in about a year, but will be getting some soon.
