What is Invicorp?
Invicorp is a combination of two active ingredients, vasoactive intestinal polypeptide (VIP; also called aviptadil) and phentolamine mesylate. Phentolamine is classified as an alpha-adrenoceptor antagonist. It works by relaxing the muscle in the walls of the blood vessels, causing the vessels to dilate, and by increasing blood flow into the penis. VIP is classified as a neuropeptide. VIP similarly relaxes the blood vessels and widens them, but also reduces blood flow out of the penis. The overall effect is that blood enters and accumulates in the penis, resulting in an erection.
How to use Invicorp
You must use Invicorp injections exactly as explained by your doctor. Invicorp is a solution supplied in ampoules or in a single-use pre-filled autoinjector device. The intracavernosal injection is given into the base of the penis. Apply pressure to the injection site for a minute or so, and if there is any bleeding, continue to apply pressure for about 5 minutes. The drug will not cause the penis to be fully rigid; this will only be achieved with sexual stimulation. Erection occurs about 5-10 minutes after the injection, and lasts between 30 and 240 minutes. The usual Invicorp dose is VIP 25 μg and phentolamine 2 mg. Do not re-inject after you have injected, even if you think that the medicine was not injected; only take the dose recommended by your doctor; and inject no more than once a day and three times a week.
Who can use Invicorp?
Invicorp is for men with erectile dysfunction. Women or individuals younger than 18 years of age should not use it.
Your doctor will want to be advised about all the medicines that you are currently taking, have recently taken or might take. You should particularly mention use of any anticoagulant treatments. Invicorp should not be used by individuals who are allergic to VIP/Aviptadil, phentolamine or to any of the other components of the injection solution. You should also not use Invicorp if you have a blood disorder, and it should be used with caution in men with blood vessel or heart disease, or have had a stroke.
Invicorp side effects
Facial flushing is the most common side effect with Invicorp. A small number of men may experience a fast heart rate, palpitations, headache, and dizziness.
Generally, the injections are pain-free and there is no pain afterwards. Effects at the site of injection, such as bruising, bleeding at the injection site, and urethral bleeding, occur infrequently, and are likely to be related to the injection technique rather than to the medicine itself. There have been no reports of scarring when Invicorp is used over a long period of time, although to minimise the risk further, alternate the injection between the right and left sides of the penis. The risk of developing a prolonged and painful erection is negligible.
What are the advantages of Invicorp?
Invicorp works rapidly after sexual stimulation to produce an erection and, after ejaculation, the effect subsides in a natural way. Another erection may be possible with further sexual stimulation. Over 80% of men respond to Invicorp with an erection suitable for intercourse. The proportion of injections producing a successful erection with Invicorp ampoules (84%) and Invicorp autoinjector (85%) is similar to that with Caverject powder (83%), another intracavernosal injection use to treat erectile dysfunction. The response to Invicorp remains over 80% in men with different causes for their erectile dysfunction, e.g. blood vessel disease, diabetes, and problems with their nerves. Invicorp may also be of use to men who have been unable to have an erection with other intracavernosal injections. Approximately three-quarters of men stopping previous therapies for erectile dysfunction because of poor efficacy respond to Invicorp. Moreover, in contrast to Invicorp, other intracavernosal injections produce painful erections, painful and sustained erections (sometimes requiring medical assistance), and scarring.

Superb product that works very well with no after pain or discomfort that I have noticed.

very good
-
I've tried a number of treatments and invicorp is by far the best!
-
Invicorp works well for me, it gives a more natural erection and the dose is ideal. i can compare to caverject which getting the right dose is more difficult and the erection feels mechanic. duration of the erection is shorter than caverject but long enough and feels comfortable whilst caverject may last longer but after a while becomes uncomfortable. if dose is too big becomes painful, if not enough penis feels sore and a semi erection is max you get. that does not happen with invicorp. overall,invicorp gives a much better experience, in my...
