PRP, or platelet-rich plasma, uses a patient's own blood and is spun down until we get only Plasma rich protein (PRP) and then we re-inject. The increased concentration of growth factors in platelet-rich plasma may stimulate or speed up the healing process, shorten healing time for injuries, decreasing pain and even encouraging hair growth. Our most popular PRP we do is the penis for increased blood vessel growth, overall size, and increased sensation.
