I don't understand how Cialas can effect libido, as its action is simply vascular. Other than the confidence you get from knowing it works well.
If anyone has any evidence that it does, please provide as to how that occurs.
on the TRT forums they tout that cialis acts as a mild AI so can balance the T/E ratio if out of whack and on a TRT dose of testosterone, seen a few case studies to back this up.
My hypothesis is most likely if you get a feeling in the johnson more than usual sex might come on your mind more often. I've been using daily cialis forever and can't say it makes a different libido wise but I've had problems with that for a long time now.
