Like Viagra, but cheaper.
Sildenafil is a prescription ED treatment containing the active ingredient, sildenafil citrate, which helps to relax the blood vessels around your penis. Erectile dysfunction happens when blood flow is restricted into the penis. It’s understood it affects around half of all men aged between 40 and 70 to some extent. So it’s more common than you might think (and if you do experience it, you’re definitely not alone). In most cases, it's also not much to worry about, but it does make getting an erection difficult.
The culprit is tight blood vessels, which stop blood flow in your penis. An enzyme called PDE5 is what causes this. Sildenafil counters the effects of this enzyme, so blood can reach the penis. And then, hey presto - a firmer and longer-lasting erection.
There are some misconceptions about Sildenafil, like it being an aphrodisiac or only for use by older men. But in reality Sildenafil doesn't directly affect sexual desire. It works by improving blood flow, making it easier to achieve and maintain an erection. Plus ED can affect men of all ages, so if you think you might have it, consult with a doctor to confirm a diagnosis before taking Sildenafil.
Because Sildenafil tablets are generic, it’s cheaper than Viagra. But it contains the same drug, so it shouldn’t be any less effective.
The process of getting erect is relaxing the smooth muscles in the penis to allow more blood flow, which causes the penis to get hard. When you have erectile dysfunction, this process is flawed. Instead of smooth blood flow, the tightening of the smooth muscles makes it restricted.
Sildenafil citrate, the active ingredient in Sildenafil, is a type of drug called a PDE5 inhibitor, which just means that it stops the PDE5 enzyme from tightening up blood vessels in your penis. This allows for more blood flow into your penis and makes it easier for you to get a harder, longer-lasting erection.
While Sildenafil can look after your physical needs, it can’t help you with getting sexually aroused.
Sildenafil tablets come in 25mg, 50mg and 100mg doses. So exactly the same doses as Viagra.
If you’re taking it for the first time, you’ll normally start on Sildenafil 50mg. If you take this dose and it works well but you get mild side effects, our clinician will suggest lowering your dose to 25mg.
Starting on a 25mg dose may also be recommended if you have any risk factors which make you more prone to side effects (like diabetes or low blood pressure for example).
Sildenafil 100mg is only for when you’ve tried 50mg and it hasn’t been strong enough. It’s the absolute maximum dose.
But before taking any medication, consult with your clinician to find the right dosage for you.
How we source info.
When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.
Take one Sildenafil tablet an hour before you plan to have sex, and swallow your tablet whole with water. It's best to take it on an empty stomach, as food can interfere with its absorption. It should take no more than between half an hour and an hour to work. Never take more than one Sildenafil tablet in any 24-hour period.
Stick to the dose prescribed for you by our clinician. If you take more Sildenafil tablets than you should, seek medical attention.
If you get any serious side effects, go to your nearest hospital as soon as possible. This includes any signs of an allergic reaction, chest pain, or an erection that lasts for four hours or more and won’t go away on its own. For more information on the side effects, check the patient information leaflet.
Clinical studies indicate Sildenafil can work in as little as 12 minutes, with the average being 30 minutes. This means after taking your tablet, within 30 minutes there should be an increased blood flow to your penis, allowing you to achieve an erection.
If you have taken Sildenafil tablets on an empty stomach and it still doesn’t work for you, get in touch with your clinician. They’ll be able to suggest a different dose or an alternative medication.

My invicorp experience
Invicorp is extremely effective and feeling is completely natural. The only thing negative I can say is the administration process is something that I find will take getting used to. I don't have an issue with needles but injecting myself isn't a comfortable task for me.
Good Job
Definitely effective for me.. I would like to know if there is any slightly stronger which would also last a bit longer & could be used safely more than 3 times a week ? Also how do i increase my monthly order ? Thankyou
Delivery problem
Don’t know what happened to my address details on my account. I had not been on my account for a long time and all previous deliveries had arrived no problem. Prescription was returned to treated by the post office due to insufficient address details. Should not have been sent if the address was incomplete. Preferred the previous carriers DPD who have a better system

Subscription with Invicorp
As before the process of adjusting my order was simple although repetitive as I don't always want a repeat exactly on the month it falls. The process is easy enough, but being able to just order when needed would be easier. However, that being said the service is amazing, extremely fast and confidential and I've never had an issue with it to date. Medication is sent chilled in my case and always arrives next day as promised.

Erectile dysfunction: Here are some other options.
Injectable treatment that works from 5 minutes. Good option if tablets haven't worked for you.
Comes as an on-demand pill that lasts for 36 hours, or as a daily dose that's active all the time.
Lower dose pill. Better option if you're older or have a pre-existing condition like diabetes.
Small pellet you insert into the tip of the penis, that works from 10 minutes.
Like Cialis, but without the branding (so it's cheaper). 'Weekend' and daily options available.
Non-branded version of Levitra. Works in the same way, but cheaper.
The one you've heard of. Works in 30-60 minutes and lasts for up to 5 hours.
Rebranded version of Viagra that comes in one dose (50mg) and doesn't need a prescription.
Cream that you apply to the tip of the penis and works from 5 minutes.
