Dr. Chan: I have been enjoying watching more than 100 of videos which you put out every week in last 2 years. Your videos are always backed up with clinical trials or research papers so they are more trustworthy. Thanks and keep up with the good works!

LOL, until recently I hadn't realized that Mario updated his favorite way to tackle ED and it's a relief! Although what he previously suggested was pretty good, it was a real pain to follow... I just go'ogled the latest in Volpstein's Erections at Will, it's so much simpler and potent now!
