I am sorry there is no injections or medicines available which can increase the size of your butt. One tried-and-true procedure, that is now being used to enhance gluteal contours, is an autologous fat injection.
This is grafting fat from one body part to add volume to another. Usually the fat comes from the abdomen, hips, back or thighs. The fat cells are removed via lipoplasty
), and then injected in "layers" into the buttocks.
