text: well you can go down to Tiajuana and buy pills there for like $7 a pill if you want to try...or talk to your doctor and ask for a sample pack the drug reps usually always leave sample packs at their offices. However....If you don't have a problem in that area then i would steer clear of those types of medications....what they do is increase the bloodflow to the vascular tisue of the penis. increasing the bloodflow for someone who doesn't have blood flow issues can possible stretch out the blood vessles in the penis, permanently damaging it...then the bloodflow that you usually had won't cause the penis to become errect and you'll be unable to maintain an erection without the aid of viagra...hence fowarth becomming dependant on it to fill the larger blood vessles. can also cause pyrines disease which is a curvature of the penis causes by stretching and scaring of the blood vessles in the penis.....just be careful bro.
