Viagra is primarily used to treat erectile dysfunction in men (which is characterized by the frequent inability to achieve or maintain hard erections long enough for satisfactory intercourse).
Viagra works by increasing blood flow to the penis, which helps get hard and full erections that last longer. Viagra also boosts your sexual energy and stamina.
This little blue pill has helped millions of men restore their sexual self esteem and confidence.
The FDA-approved Genuine Viagra is only made by Pfizer Inc, which hold the worldwide patent for sildenafil citrate (Viagra's active ingredient and generic name). Pfizer-made Viagra is also known as brand name Viagra.
On the other hand, some other pharmaceutical companies manufacture generic versions of Viagra under different brand names and shapes, but allegedly with the same active ingredient (sildenafil citrate). None of the generic versions of Viagra have been approved by the FDA and none are manufactured legally.
In addition to that, studies and clinical tests have found that most "cheap" generic Viagra sold online contain unapproved, unknown, or dangerous ingredients.
So, if you must purchase generic Viagra make sure you only get it from a reputable supplier that other users would recommend.
Viagra is approved and classified by the FDA as a by-prescription-only medication, and so it is not recommended that you try to buy it with no prescription.
Most people want to buy Viagra online without a prescription, most probably because they are "embarrassed" to talk to a doctor about their sexual problems. That's why most licensed online pharmacies provide a more convenient and discreet way to order Viagra without having to see any doctor.
Online pharmacies that sell authentic Viagra (like the one we link to below) will ask you to fill out a special online medical questionnaire and submit it for review by a licensed doctor who works for the only pharmacy. If their doctor decides that Viagra is safe for you (based on your submitted medical data), your order will be processed and a prescription with your name on it will be shipped to you discreetly with the pills.
Viagra is taken orally about 30-60 minutes before sexual activity. It stays active in your system for about 4 hours, during which you can enjoy full functional sexual intercourse with rock hard erections.
Viagra comes in three doses: 25mg, 50mg, and 100mg. The 100mg dose is the most effective and popular one, with which most patients have experienced and reported the best results.
You should always follow the instructions provided on your prescription for the best and safest usage of this medication.
