Alprostadil
"I had difficulties achieving a full rigid erection since my teens and never found satisfactory treatments until I was 23 when I emotionally opened up to my doctor with tears. I was sent for a Doppler scan of my penis to figure out what's going on. It turned out my left artery on the left side is narrow and I had a birth defect. My doctor showed me how to inject myself and found my dose of 14 mcg. I have not changed the dosage for 14 years. Viagra, Cialis etc. do not help me due to the birth defect. I use the prostaglandin E1 carefully and I think it's a great. I gave it 10 rating. It works."
