erectile dysfunction
"This medication worked well for me! 200 mg and I was rock hard for hours wow. Viagra was weaker for me I don't know why. I got burned by a topical medicine cream [FDA is a joke and a half] anyway insurance will ONLY sadly pay for 6 pills a month] sick right? very very sick. Anyway this worked better for me than viagra. Reason being is must be genetics that .1% difference in humans does make a huge difference for medical compounds. Also Avanafil is structurally different vastly from Viagra. Nitric Oxide effect is increased  therefore GMP increases thus leading to better erections. Try all PDE 5 inhibitors before you say they won't work because what may work for one may NOT work for another."
