Comparison of Viagra, Levitra, Cialis

Which one is better? I will answer the question. Currently, there are three types of ED treatments: Viagra, Levitra, and Cialis. For over 20 years after Viagra was released, the only ED treatment was Viagra, so I wasn’t confused about the choice, but if there are three types as it is now, which one is better? How should I use it? I’ve come to hear a lot of voices saying I don’t understand. Therefore, it is easy to understand, and a comparison of each ED treatment drug is summarized in the table. Since there is a difference between the effect of food and the onset time and action time, it is good to use it properly depending on the situation. Basically, Viagra, Levitra, and Cialis all work within an hour, so it’s okay to take them one hour before the act. Viagra is a good choice for name and security, Levitra 20mg for speed and strength, and Cialis 20mg for long-term action and easy to use. Cialis is recommended if you eat on a date and cannot measure the time to act, or if you want to make the drug work untill the following day. The duration of action of the drug doesn’t mean staying erected during that time, but means the time of erection in response to a stimulus, so there is no need to worry about the duration of action for being too long and it does not interfere with daily life.
