viapren dosen't work, and isn't free.it's a fraud!
exactly 1 week after i received my "free" sample i received a full month's supply and a bill for $48.00. I was not given the time to cancel before it was shipped, as I was told on the phone. I can now see why these newspaper ad products are not available in retail stores, this is the second product I tried that turned out to be fraudulent. I was trying to get something that I didn't have to get from a pharmacist.
I now use Viagra, it may be expensive, but it works.
