Sildenafil
"Viagra has been an absolute miracle for me. For a while before I started taking it I was having trouble getting and maintaining strong erections. The best I could manage was a "semi" where my penis would get to around 60% hardness. Erectile dysfunction is difficult to deal with for men of any age, especially so when you are in your 20s (I'm 24) and are supposed to be at your peak sexually. I'm using the 25mg Pfizer tablets and they work amazingly well. No side effects. I now have very strong and rock hard erections. I'm a much happier and relaxed man now. It is quite expensive but they are worth every penny."
