Viagra is a specific drug available only by prescription. It is not a vitamin or herbal remedy. While some of these remedies may not be harmful, they probably won't give you the results you're seeking, and you'll have spent a lot of money. If you think you need Viagra, you should talk to your doctor and be sure you get a legitimate prescription.
