Answer:
here is some info from the site i use (below)
What does the term "generic" mean? Do generic medications produce the same effect that the brand name medicines do? >>> The difference between a brand name medicine and a generic one is in the name, shape and in the price. A generic drug is usually called by the name of the active ingredient while a manufacturer uses a brand name. However, a manufacturer cannot possess a patent for a certain chemical agent, this is why manufacturers of generic medications can legally produce the so-called "generics". They are the same chemically and since the active ingredient is identical, they have the same medical effect. Thus buying a generic medication one pays less but gets the very same result.
Why are generic medicines so cheap? >>> Unlike generic drugs, a large part of the costs incurred by original manufacturers of brand name drugs are for research and development and advertising. The expense of obtaining FDA approval alone in the U.S. is enormous. Manufacturers of generic drugs do not have to absorb or recover these costs. Consequently, significant cost savings can be passed along to you.
Bottom line, same chemicals in the same percentages but no fancy labels or boxes. works for me :)
~I have no idea what "sialis" is, but generic is supposed to be as good as the brand name, but side effects CAN be different. Some things are added in generic that aren't in brand names. Side effects between the two are considered rare.
Since your question is about "viagraor" Viagra? Look it up on webmd or ask your doctor.~
You don't need either unless you have been diagnosed with erectile dysfunction. These medications are not meant to be taken casually nor do they enhance any other sexual function. Read the side effects and take them only if prescribed by a doctor.
Generic Viagra is Sildenafil Citrate, Generic Cialis is Tadalafil and Generic Levitra is Vardenafil HCL. A great source for the purchase of those in generic form is http://www.4rx.net
As stated by another user, DO NOT use these meds unless you NEED them. They are not party drugs. They will do NO benefit for you if you DO NOT need them, but they can harm you if you use them and dont need them.
If you truly need them for erectile dysfunction, they are a godsend.
Hope this helps
Are you in the US? If so, none of these drugs are approved in the US as generics. If you are thinking about buying them through mailorder, beware. Most likely, they are counterfeit, and may not even contain the active ingredient and may be dangerous. If you are in another country, please indicate that - I can look to see if they are officially available there.
