Hi Mike, First have you googled
Bystolic and erectile dysfunction, if not you should makes for some intresting reading for you and ED.
Have a read up on cayenne pepper and HBP, they say it equals out blood pressure out, then you just stay on that, google cayennepepper( one wrod) for blood pressure, it will also clean out any plaque from your blood and look after your prostate, and it help your ED, all from one thing, cant be that bad can it.
