The journal International Society for Sexual Medicine recently reviewed ingredients found in top-selling “nutraceuticals” — a category that includes nutritional supplements and herbal teas — promoted as remedies for E.D.
The reactions of the supplement on the males were recorded including all improvements in sexual performances.

Our ED medications are cheaper than branded alternatives because they are “generic” medicines. A generic medicine is one that has been created to be the same as an already marketed brand-name medicine in terms of dosage, safety, strength, quality, how well it performs, how it’s administered in the body, and what it’s used for. Branding a medicine costs pharmaceutical companies a considerable amount of money, and this cost is usually shifted on to consumers in the form of higher prices. However, generic medicines are unbranded - which means these costs do not get passed on to the consumer. As a result of this, generic medicines are almost always cheaper than branded alternatives (even though they contain the same active ingredients and work in the same way).
If oral medications are not effective or appropriate, there are other treatment options for ED. Alprostadil causes an automatic erection by increasing blood flow without sexual stimulation. It is available in an injectable form, with a small needle used to inject it directly into the base or side of the penis. It is also available as a small pellet that is inserted into the urethra (opening at the tip of the penis). It can cause side effects including priapism (an erection that does not go away) and tissue scarring.
