Haven't seen any testimonials, but there is an interesting procedure called Priapus . It involves PRP therapy. A vial of blood is drawn from the arm, then is spun and separated. The platelets are combined with another substance, then injected into the penis. Supposedly, an immediate response takes affect. The penis increases in length and girth. After a while, it subsides, but gradually an improvement is seen in most cases.
Anyone else hear of this? Google it.
