ADC does sell generic versions of Levitra and Cialis. I have ordered both from them at drastically reduced charges compared to the medications that we order in the USA. Both versions that I have ordered from ADC seem to work as well as the original drugs, which in my case, means that they truly don't work well, but that is just me, and my ongoing post-surgical ED issues. I continue to take the medications as a form of rehabilitation, as prescribed by my Uro physician.
When you order the Cialis product from ADC, it is named "Ceebis", and they require you to email them a statement that states that you will not consume the medication within the USA. Once you have submitted that statement, they will process your order and it will take approximately two weeks to receive the medication in the mail. The generic version of Levitra from ADC does not require a similar statement.
Hope that this information will be helpful to you. Good luck with your ED issues.
