This is a question geared toward genes nitric oxide stack. I keep reading on a lot of forums that people are taking 5 mg twice a day. I also keep reading that 5mg of Cialis is the only safe daily dose. I am currently taking 5mg a day and would love to take it twice a day for the NO2 benefits. What are your sources of taking 5mg of Cialis twice daily as being safe? Thank you very much for your time.
