V i a g r a substitute Cialis and Levitra
Cialis, V i a g r a and Levitra all are the same medicine to treat Erectile Dysfunction. I think V i a g r a and Levitra is the best option for men.
V i a g r a, Cialis and Levitra contain very similar active ingredients and essentially work in the same way. The biggest difference between the treatments is that Cialis is effective for a period of 36 hours, during which it helps you get an e r e c t i o n. Both Levitra and V i a g r a remain effective for 4 hours, and need to be taken 30 minutes to 1 hour before s e x. Cialis tablets can be taken in the morning and will still be effective in the evening.
