Generic Viagra was launched in 1998, about four years before Generic Cialis, so it has been proven for more years. Despite that, Generic Cialis is said to work faster and for longer time (up to 36 hours in some men).
This drug is a usual comparison due to their effectiveness. It is difficult to choose between them.
In order to get the best for you, discuss with your doctor the right treatment based on your medical history and general condition.
Remember, Generic Cialis vs Generic Viagra is not a real battle; it is only the possibility of two good options.
