Viagra is a drug that helps men with dysfunctional erectile ability to achieve and maintain erection for as long as it takes to have a fulfilling sexual act. Its active ingredient is sildenafil, a powerful vasodilator that relaxes smooth muscles in the penis, promoting maximal blood absorption and retention. Sildenafil can be found in different dosages, forms and at varied prices at Family Pharmacy Mall, which I am actually quoting now. There you can find all the necessary information on the drug and ask them questions, they respond fast and in great detail, helping to avoid the usual pitfalls of all beginners. Good luck with your therapy!
