Erectile Dysfunction
"I am 72 years old. I tried Viagra, it worked but to many side effects, I tried Cialis and it really never worked for me, but it also caused severe delayed back pain which lasted a couple of days each time I used it. 

I have been using Stendra 100mg for a little more than a year  and it works for me with out any side effects. On some days I am able to get a second erection several hours later."
