erectile dysfunction
"64 yrs old, difficulty sustaining an erection, have tried Viagra, Cialis, Levitra and now Stendra.  Viagra gave me irregular heartbeat, Cialis gave me the worst headache and severe facial flushing but worked great, Levitra had lesser side effects but stopped working despite increasing the dosage.  Have used Stendra about 4 months now, have had to increase the dose steadily, now it is effective at 250 mg and still very limited side effects, a slight headache sometimes, no body or back ache, slight facial flushing, so basically it is the best erectile dysfunction medicine I've yet tried."
