Sildenafil Reviews: What Real People Think Of Sildenafil

Sildenafil, the generic form of Viagra, is one of the best-selling erectile dysfunction drugs of all time.  Not only is it extremely effective in treating ED in most men, but it’s generally seen as quite safe, affordable, and convenient.  As the prevalence of ED increases with age, the development of sildenafil and other oral ED medications has been a boon to the sex lives and sexual fulfillment of an aging population in the US and abroad.  One of the best ways to see the positive effects and gauge customer satisfaction with a product is through reviews and customer feedback, of course.  To that end, we’re going to look at some sildenafil reviews below, from customers who have purchased sildenafil (generic Viagra) from Invigor Medical, to see how it has worked for them. 

Of course, every person is unique and responds to medications in their own way.  Just because some or many others have given positive sildenafil reviews and had success with the medication does not guarantee that you will.  The body of evidence suggests that the vast majority of men can see anywhere from mild to significant gains in erectile function from the class of drugs (PDE-5 inhibitors) to which sildenafil belongs.  Still, it’s always worth mentioning that if you are suffering from ED and considering sildenafil – or any other treatment – you should thoroughly discuss your options with your doctor or prescriber.  Be sure to discuss any medical conditions, other medications you may take, vitamin supplements, and herbal remedies, to ensure that sildenafil is right for you. 

With that disclaimer out of the way, let’s cover some basics of what sildenafil is, and how it works, before moving on to our top sildenafil reviews that we’ve received from satisfied customers at Invigor Medical.  

What Is Sildenafil?

We’ve written more extensively in other articles on our site about sildenafil and the molecular mechanisms of how it works.  However, in the context of this compilation of sildenafil reviews, we thought a brief revisiting of the basics of sildenafil was in order. 

How and Where to Buy Generic Viagra online

Sildenafil is a type of oral medication designed to treat erectile dysfunction.  It goes to work within 30 minutes to two hours, and its effects last for 3 to 5 hours in most patients.  It is known as a PDE-5 inhibitor because it’s mechanism of action is binding to the enzyme, PDE-5, thus inhibiting its natural function for a time.  PDE-5 is normally found in the body and works in the chemical pathway, which inactivates the effects of nitric oxide.  Since nitric oxide is an essential component of achieving and maintaining an erection by increasing blood flow, reducing PDE-5 functionality increases functional nitric oxide levels making it easier to get an erection suitable for sex and maintain it. 

Sildenafil Availability

Until recently, sildenafil was only available under the brand name Viagra.  However, it has now gone off-patent and is produced as a generic medication.  Whether purchased as sildenafil or Viagra, it is only available with a prescription.  A patient must be prescribed sildenafil to treat erectile dysfunction, after consultation with their doctor.  While it is considered safe with few side effects, all medications have the potential to cause adverse effects.  Abuse or misuse can also lead to harmful complications, up to and including those that may cause permanent damage to the penis.  Therefore, men must discuss all the details of their health conditions, medical history, and medication portfolio with their health care provider to ensure that sildenafil will be well-tolerated and won’t interact with anything else being taken.

Sildenafil Reviews And Feedback From Customers

Without further ado, let’s get to some of the top sildenafil reviews we’ve received as feedback from our customers.  These reviews may be about their experience in obtaining sildenafil from Invigor Medical, the efficacy of the medication itself, or any other aspect of the consultation, prescribing, and treatment process with sildenafil.

“It was always too embarrassing to bring up my erectile dysfunction with my doctor in person.  I’d gradually gotten used to not having much of a sex life anymore, but felt like I was disappointing my wife.  The option to see a doctor remotely online and get approved for sildenafil made things much easier.  The distance and video chat appointment made it easier for me to discuss my concerns and issues and seek treatment.  I’d always heard about Viagra and how great it was, and now I wish I had had the courage to talk about ED earlier.  Two thumbs up from this satisfied guy (and his wife)!”

Jose H., Riverside, CA

“As I have gotten older I have seen a significant decrease in my ability to get hard and stay hard, if you know what I mean.  Sildenafil pills have done the trick for me.  I just take one about an hour before doing the deed.  I can satisfy my lady, and the worst side effect I have ever had is a bit of redness and flushing in my face.  In other words, it works great and gives me back the same kind of abilities below the belt that I had when I was younger.”

RL, Plano, TX

“We’ve all had those spam emails about buying Viagra online before.  I was skeptical at first, but this is nothing like that.  Invigor Medical’s online doctor appointments are real, the doctors are real, and the pills are real.  They work as advertised and the prices are very affordable for the average person’s sex life.  Sildenafil generic is just the same as brand-name Viagra, but doesn’t cost an arm and a leg.  Exactly what I needed!  A+ service!”

Frank, North Hempstead, NY

“ED is nothing to be ashamed of.  It happens.  You can mope and do nothing, or you can take action.  Give sildenafil a try.  Online doctors are easy to work with and talk to.  You don’t need to take a [prescription] to a pharmacy either.  They handle it all and ship the pills to you.  It’s great.”

Anonymous, Tampa, FL

“Ever since I started taking antidepressants, my buddy downstairs hasn’t been his old self.  I can’t stop taking the antidepressants, but don’t want to go without a sex life, either.  We don’t always have a lot of health care options here in Alaska, either.  Getting [sildenafil] online was the right decision.  No hassles, I can stay on my antidepressants, and my buddy is back to normal.  Each pill is only a couple of bucks – totally worth it.”

Tyler, Anchorage, AK

“My experience with sildenafil has been great.  I think my bedroom performance is even better now than it was before my erectile dysfunction started.  And I have never had any side effects or problems with it.  I was wary of getting medication online but [Invigor Medical] is legit.”

CJ, St. Louis, MO

“Getting a prescription for sildenafil is probably the best decision I’ve made for my sex life ever.”

Larry S., Chicago, IL

“I wish I’d known about generic Viagra and Invigor Medical sooner.  Great service, makes life so much easier.”

Eric, Norfolk, VA

“For people like me who live on a fixed income, price is always a consideration for buying medicine – especially one that could be seen as a “luxury”, since sex isn’t as important as eating or having a roof over your head.  But ED takes a toll on you over time and your relationships.  Price shouldn’t stand in the way of that, and generic sildenafil makes it much more affordable to prioritize sex in your life once again.”

Anonymous, Easton, PA

“I would write a thousand sildenafil reviews for your site if I could!  From someone who was afraid to talk to their doctor, this service is a God-send.  There’s something about not being face-to-face that removes some of the embarrassment.  Getting ED meds online like this is easy and convenient.  I looked at a lot of places that sell them, and Invigor has some of the lowest prices overall when you include the appointment price compared to other sites.”

Dennis, Akron, OH

“Sildenafil reminds me of that Austin Powers movie – it’s like getting your mojo back.  I feel like I’m 20 again.”

Rich, Henderson, NV

“I was really worried that if I took [sildenafil], I’d be walking around with a boner for hours for no reason.  It doesn’t work like that at all.  It works when you need it to only, not randomly or at inconvenient times.  I’m very happy with my results.”

S.P., Greensboro, NC

“For people who don’t know, there are other online sites that offer sildenafil and ED meds, and even advertise a lot on TV and adult sites.  But when you look at the total price – appointment/consultation, meds, and shipping – this site is usually the smarter choice.  You can enjoy a 3-4 hour sex session for less than your daily coffee habit at Invigor.  I call that a win.”

Bob, Decatur, GA

“In my life, I’ve had a lot of issues with medication side effects.  That made me worry about taking anything for erectile dysfunction for a long time.  I finally tried sildenafil, the generic Viagra medication, and I couldn’t be happier.  No side effects except an occasional headache a few hours after me and the missus have finished up.  Small price to pay for being intimate once again.”

Walter P., Maple Grove, MN

“Let’s be honest: no guy wants to deal with erectile dysfunction, or talk about it.  But you should.  A simple pill can treat it, and it’s easy to get.  A half hour of video chat is all it took me.  Way less stressful than going to the local doc, and problem solved.”

Vince, Springfield, OR

“10/10 service and value for Invigor Medical, and 10/10 for performance and effect for sildenafil. 

Anonymous, Laramie, WY

“Never been happier than after finding sildenafil for a reasonable price.”

Steven B., Yuma, AZ

Frequently Asked Questions

How Can You Make Sildenafil Work Faster?

Sildenafil typically takes between 30 minutes to two hours to work, though most men start to see effects within the 30 to 45-minute range.  The variability stems from the fact that, as with most oral medications, it needs to be digested and broken down in the body.  The rates at which one person digests and processes oral medications will vary from the next and depend on many factors.  However, one sure-fire way to maximize the speed at which sildenafil goes to work is to take it without food, several hours after or before your next meal.  This helps the digestive system to solely work to process the medication rather than having to burn through a bunch of other food compounds at the same time.

What’s The Normal Dose Of Sildenafil?

The usual minimum dose of sildenafil is 25 mg, with the maximum recommended dose being 100 mg.  Most providers offer 100 mg pills and advise you to break them in half, thirds, or quarters when you first start taking it.  You should always use the lowest effective dose, as that reduces your risk of side effects.  Taking more does not prolong the effects or result in more powerful effects, either – it only risks complications.  Do not take more sildenafil than prescribed, or you can end up with an erection that will not go away on its own, a medical emergency that could result in permanent damage to your penis.  

Can You Take Sildenafil More Than Once A Day?

No.  Sildenafil and other oral ED treatments are designed to be taken no more frequently than once a day.  While the medication’s effective period is only 3 to 5 hours, that does not mean all of the medication is eliminated from the body in that time.  Taking more than one dose per day can lead to an overdose, and drastically increases the risk of developing priapism, a painful and persistent erection that will not go away on its own, a medical emergency requiring immediate medical attention to avoid permanent damage to the penis.  Only take sildenafil as prescribed, and no more than once per day. 

Concluding Thoughts

The above are just some of the sildenafil reviews that we’ve received from our customers.  They are meant to provide insight for new customers, who are considering sildenafil to treat their ED for the first time, or who may be considering Invigor Medical for the first time.  We encourage you to read the other articles about sildenafil on our site, in addition to these sildenafil reviews, to get a good sense of what the medication is, how it works, and the experiences of real people with taking it for ED treatment.  Then, when you’re ready, schedule an online consultation with Invigor Medical, and talk to one of our doctors about your ED and treatment needs. It should also be noted that because Sildenafil and other oral medications only play a single role in supporting sexual function, there are a number of other options to improve your sex life. For example, many clients who purchase Sildenafil or Tadalafil, will also buy PT-141 injections to increase sexual drive in both men and women.
