People always ask "Where's the best place to buy Viagra?" We
investigated the top websites that sell Viagra before we wrote
this page. We learned what to look for in order to find legitimate Viagra websites.
You need to know that:
- Half the Viagra sold on the internet is fake.
- Most of the websites that sell Viagra are located in 3rd world countries but they lie and pretend to be American or Canadian.
There is no such thing as an FDA approved generic Viagra. The government considers generic Viagra to be an illegal substance.
The Feds are concerned that it may be unsafe because you have no way of determining the quality control that went into making the generic Viagra. They don't go after the people who buy it, but postal inspectors will confiscate it if they find it.
There are lots of websites that sell generic Viagra without a prescription. Some people swear by it but you are taking a chance with your health if you take generic silendafil, especially if you do so without the knowledge of your doctor.
Things To Be Suspicious Of:
- You want to make sure there is a physical address on the
website selling the Viagra. It should be a real address, not a P.O.
box. If there is no address that is a bad sign.
Why would someone want to hide their address? No address means
that they are deliberately making it hard for you to track them down
in case there is a problem.

Viagra Buying Tips
- The website selling the Viagra should have a toll free telephone number. If something goes wrong you want to be able to speak to a real live person. It is very frustrating to only be able to communicate by e-mail when you have a problem.
- Test the telephone number before you place your order. Ask
the person who answers the phone where the product is shipped from.
If they don't answer to your satisfaction, it's a bad sign.
- Do they have a 24-hour chat or IM customer service? The reliable, established internet pharmacies all have this service integrated into their sites. If they have such a service, test drive it.
How long does it take for the person on the other end to respond? Ask them some questions such as: "how long have you been in business? Who is the manufacturer of your Viagra? Where is it shipped from? How long does it take to get my shipment.
- Ask them if they do the shipping and handling or if they only do the billing.
There is a good chance that the person on the other end of the phone
is just a go-between; a clerk in front of a credit card machine, doing the billing for hundreds of Viagra websites.
In many instances, they have no idea who the Viagra merchant is; all
they know is that once a month they get a commission check from
someone they have never seen or met in person.
Their job is answering the phone and ringing up your sale. After your
credit card has been charged, the relationship is over.
- You get what you pay for. If it seems too good to be true, it
probably is too good to be true. You are better off paying $10.00 per
pill at your local drugstore and getting genuine American Viagra than paying $6.00 for a so-called generic Viagra on the internet and getting a fake.
- Your first purchase should be for a small quantity of pills. Don't start of with thirty tablets. Buy five or ten. Make sure the Viagra is legit and the shipping and billing goes smoothly before you make a large purchase.
You should never deal with a site from Russia or Nigeria, places where identity theft is common. Scammers in these countries have been known to set up sham Viagra web sites just so they could steal your credit card information.
Did you know that Pfizer (the only legitimate manufacturer of Viagra) has a program whereby they offer one free Viagra tablet for every 3 pills you buy? Click Here to view the Pfizer Value Card.
Who does this site recommend?
If you are looking for brand-name Viagra manufactured by Pfizer Laboratories, without a prescription, I recommend AccessRx.com. They have been in business since 1999. They are located in the USA in Tempe Arizona. They offer overnight shipping.
They have a 24 hour telephone number for customer service. They even have licensed physicians and pharmacists on staff to answer your medical questions.
I can vouch for AccessRx.com because I am friends with AccessRx.com's director of Marketing, Richard Bernstein. Mr. Bernstein takes his business seriously and takes pride in his company's track record and reputation.
Their prices are higher than the generics but you are assured of getting brand-name, American, FDA-Approved Viagra delivered to your door in a couple of days without having to go to a doctor.
Where does fake Viagra come from?
Most of the fake Viagra comes from China and South America where the laws regarding pharmaceuticals are lax.
Most of the Viagra selling websites are fly-by-night operations looking
to make a quick buck. They often masquerade as American or
Canadian internet pharmacies but they are usually located outside the law in countries such as Cambodia or Bulgaria.
Real or Fake? What's The Big Deal?
Many sites sell counterfeit Viagra to unsuspecting people at highly
inflated prices.
Sometimes they sell you a little baggie of half-tablets and Viagra
crumbs. And when you try to call the "1-800" telephone number on
the site you brought the pills from to complain, all you get is the
run-around.
A common scheme is that people try to sell you sell so-called
generic Viagra that contains no active ingredient. The poorer the country is, the easier it is to bribe local officials to look the other way.
One hundred dollars goes a long way out in the boondocks of China or Mexico. If you live in one of these countries, it is easy to open a pill factory to manufacture fake Viagra.
These little factories are like meth labs - they stay open a short while, manufacture several thousand bootleg or counterfeit pills and move on before they get caught.
In the US, Viagra costs no more than $9.00 or $10.00 per pill. When you buy Viagra on the internet prices vary by as much as 50% so it pays to comparison shop.
If you buy a larger quantity you should pay less per pill. If you buy a
smaller quantity you will pay more per pill.
In general, the farther away the Viagra seller is, the easier it is for
them to rip you off.
Avoid buying Viagra from Asia, South America, Mexico and the
Caribbean because that's where a lot of the fake Viagra comes from.
Another reason to avoid buying Viagra from outside the United States
is the pills might be confiscated by postal authorities when they reach
the United States.
This is happening more and more each day as the FDA and the DEA
crack down on the illegal importation of drugs into the USA.

What Is Viagra and How Does It Work?
All three of the erectile dysfunction drugs (Viagra, Levitra and Cialis)
are similar in action. They block an enzyme that causes an erection
to go flaccid. Although these drugs are similar in action, their dose,
onset of action time and duration of action differ.
Viagra (Sildenafil) is a member of a family of drugs called PDE5
Inhibitors. Viagra was the first PDE5 inhibitor on the market. FDA
was approved Viagra on March 27, 1998. The team of scientists
who discovered Viagra won the Nobel Prize.
The BIG Discovery: cyclic guanosine monophosphate (cGMP)
Some very smart scientists discovered that cyclic guanosine
monophosphate (cGMP) was the key to sustaining an erection.
They discovered that when a man gets sexually stimulated, a chain
reaction occurs in the tissue of the penis that results in elevated levels
of a substance called cyclic guanosine monophosphate (cGMP).
As long as there are sufficient levels of cGMP, the penis can remain
erect. The more cGMP, the more robust and durable the erection.
If you inhibit the degradation (breakdown) of cGMP it stays around in
the penis longer, producing a more durable erection.
Another way you can think of Viagra (and all other similar medicines)
is that it preserves the elevated levels of cGMP that are created when
a man is sexually stimulated for a stronger, more lasting erection.
That's how Viagra works - Viagra blocks the enzyme
phosphodiesterase-5 (PDE5) which is responsible for the neutralization
of cGMP. Viagra (Sildenafil) is a highly selective inhibitor of PDE5. (PDE5 is not the only phosphodiesterase involved in the erectile
physiology but it appears to be the most important one).
The nice thing about PDE5 blockers is that they shouldn't cause
erections at inappropriate times because they only block degradation
of cGMP produced in reaction to sexual stimulation, such as thinking
about something sexy.
If you are not being sexually stimulated, there is no cGMP to protect,
so the drug remains in the background.
Non-Sexual Uses For Viagra:
The active ingredient in Viagra (silendafil) is useful in treating a rare, potentially deadly condition known as pulmonary hypertension.
In this use, Viagra's Phosphodiesterase 5 blocking activity is thought to be beneficial in relaxing the smooth muscle tissue found in the lungs by increasing the levels of cyclic guanasine monophosphate (cGMP).
Pfizer sells a tablet called Revatio for this use. Each Revatio tablet contains 20mg of silendafil (the active ingredient in Viagra) and it is taken 3 times a day aproximately 4-6 hours apart.
Absorption, Bioavailability
Viagra is rapidly absorbed. Maximum observed plasma concentrations
of Viagra are reached within 30 to 120 minutes (median 60 minutes) of
oral dosing in the fasted state. Viagra is about 40% biovailable. Viagra
is highly protein bound (96%). When Viagra is taken with a high fat
meal, the rate of absorption is reduced.
Metabolism, Half Life, Excretion
Viagra is mostly metabolized in the liver by an enzyme known as
CYP3A4 and to a lesser extent CYPC229. Viagra breakdown products
are excreted in the feces (80%) and in the urine (approximately 13%). Viagra's mean half life is about 4 hours.
If you are going to take any of the PDE5 inhibitors such as Viagra, it is
very important that your doctor be aware if you have a liver condition
(such as cirrhosis) or kidney condition ( such as if you are on dialysis)
because you may need a special dosage adjustment.
Likewise, if you try to obtain Viagra on the internet, please make sure
that the person authorizing your prescription knows the true status of
your liver function and your kidney function.
Dose:
For most patients, the recommended dose of Viagra is 50mg taken about 1 hour prior to anticipated sexual activity. However, the Viagra label states that it can be taken anywhere from 1/2 hour to 4 hours
prior to sexual activity.
The dose of Viagra may be increased to 100mg or decreased to 25 mg
depending on efficacy and side effects. Sometimes people buy the
100mg tablets and break them in half to save money.
Viagra is available 25mg and 50mg and 100mg tablets.
The maximum recommended dose is one pill per day.
