How quickly does Viagra take effect?
Normally It can take as long as an hour, but for many men, the results come in 20 minutes. Most doctors start their patients on 50 milligrams of Viagra but, according to the results, may later alter the dose up to 100 milligrams or down to 25 milligrams. It may take four or five experiences using Viagra before you could learn the optimum dosage and timing.
