I have been treated for heart disease for past 30 years. On numerous medications including Plavix, Lipitor, metrapol (lowers blood pressure, thou I never had high blood pressure), Zetia, aspirin, folic acid. Completed prostate cancer treatment almost a year ago. I feel fine, except suffer ED. . What are your thoughts of taking Pycnogenol 50mg 2x/day and Arginine 2000mg (recommended by friend for ED) with my other medications
