Iam 79 in great health, no meds, blood pressure 120 over 80, no cholesterol problems, however, I suffer from erectile dysfunctiion, viagra (sildenafil) helps a lit?

Age only. Keep it up. Take your vitamin, keep exercising, eat what you have been eating. You may need an increased dose of the viagra, (sildenafil) but only after you doctor checks your testosterone level. If you have any chest pain with the medication, please let your doctor know immediately. You are amazing!
