In an erection, impulses from the brain and local nerves cause the muscles of the corpora cavernosa, two chambers in the penis, to relax and allow blood to flow in through the arteries and fill the spaces. The engorged chambers expand the penis and the tunica albuginea, a membrane covering the two chambers, helps to sustain the erection. The erection ends when muscles in the penis contract to stop the inflow of blood and open the veins for blood outflow.
The unique formula in Endowinex allows the arteries in the penis to relax. During arousal these relaxed arteries pump a substantial increase of blood flow into the corpora cavernosa, creating a bigger, harder, longer lasting erection. The best part is, it's all natural! You won't suffer from heart palpitations, stuffy nose, blood shot eyes, headaches and all of the other side effects that come from prescription medications.
