 Matt Coker here with West Coast Men's Health. In the past five years, we've seen thousands of men at our clinics. Most guys tell us the same story, that in their early 50s, it's not that they couldn't function, they just needed help. They started taking Viagra, and it worked great at first. But after a few years, it stopped working. The problem is that their arteries had become more restricted since they started taking it.
