"Many men, including myself, suffer from ED (erectile dysfunction).  I tried all of the medications available in the United States, and found sildenafil, the chemically active ingredient in brand name Viagra®, to be the most effective. Unfortunately, the cost of brand name Viagra® is prohibitive, and generic sildenafil is not currently being manufactured in the United States.  So I began to search for an alternative. Over the years, I mostly encountered fake or counterfeit products.  After all, sildenafil is the number one counterfeited medication worldwide. Fortunately, after many years of searching, I found a reputable pharmaceutical labaratory in Central America, with fabulous standards of purity and safety who manufacture sildenafil tablets. My investigation showed that these tablets are indistinguishable from brand name Viagra® tablets purchased in this country, at less than 1/4 the cost

How does sildenafil work?

Sildenafil enables many men with erectile dysfunction to respond to sexual stimulation.  When a man without ED is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis.  As the arteries in the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood flow out of the penis.

With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection.  However, if the nerves or blood vessels associated with this process aren't working properly, a man may not be able to get and keep an erection.  Sildenafil increases blood flow to the penis, so that when a man is sexually aroused, his penis become erect.  When the sexual encounter is over, the erection goes away.
