Greetings, GB. I have used ADC (all day chemist) two times. The first time I ordered their version of Levitra. The second time I ordered mostly their version of Levitra and a few of their version of Cialis. I say their version because as I understand it they are not technically generics. They are simply the version that is compounded in India. When I ordered the second time I received an email from ADC saying that they are not able to ship their Cialis product to the USA for consumption in the USA. I emailed them back and said I travel fairly frequently overseas (London in July, Johannesburg in Dec, etc.) and they emailed back and said they would ship.
I had used both name brand Levitra and name brand Cialis from samples my doc gave me. Both seemed to work at all strength levels. I had thought that Cialis would last longer and thus I might want to go that route more than Levitra. I have come to the conclusion that while both work, I prefer the ADC version of Levitra to everything I have taken. By the way, I've never taken any form of Viagra. My doc says it works differently than Levitra or Cialis and uses it only if the first two don't work.
Trust this helps. Let me know if I can help further. David
