Did you guys see that special on MSN NBC? It was showing how many fake viagra is out there. Even some pharmacys are being sold fake pills. It was amazing how people were being fooled. It looked exactly like the real viagra, box, pills, special logo, everything.... They said be especially careful when buying over the internet. The program was showing about 80 to 90 percent of viagra sells on the internet was most likely fake. If you know of a source where you took the stuff and it definetly helped please post it hear. I really start to wonder if some of the pills I took were fake... sometimes they seemed to work and sometimes they didn't......
