Not much difference in sought-after results, but Cialis interacted with my blood pressure meds, causing me to faint and wind up paramedics taking me to an ER and hospitalization.
That let me to the penal injections. I had resisted them for psychological reasons; the idea of voluntarily sticking a needle into my penis was too much to overcome. But once there, the results were quicker, better, longer-lasting, and safer when it comes to side-effects. It is an option that has been around much longer than Viagra and the copy cat pills that followed.
