Thanks for your comment. Penile injection therapy must be individualized as to the potency and dose of the formula due to differences in severity of ED and as to the needle length due to differences in penile shaft thickness. I worked part time for a multinational company which exclusively operates ED clinics where the vast majority of patients are prescribed penile injection therapy because they did not respond to oral medication, e.g. Viagra, Levitra, Cialis. I have treated thousands of patients with this therapy. I can only provide my best recommendation to the OP’s concern. Whatever one gleans via an internet search does not necessarily reflect the practice of physicians around the world who, like I did, specialize in penile injection therapy for ED. Most urologists do not prescribe this on a frequent or regular basis because it is very time consuming. Their major focus is on urological procedures and surgery.
