"Nurse here.
This is a bad idea. All you folks saying to do it need to think more about what a pde5 inhibitor does. it selectively dilates certain vessels in the penis and pulmonary artery. Overall blood pressure is lowered by 2 to 0.5 mmHg. That is not significant.
Seeing a doc for this is cheap. For high blood pressure, you need proper bp meds."
Thank you... that's what I'm talking about, people that know more than my broscience weighing in. If I know something for sure, I try to cite it.
