Hi: I understand you are 19 yrs and wanted to increase your height. The stature of an individual is determined by the genes, bones, hormones and nutrition. Treatment would be effective, only if your bone ends are open and have the capacity to grow. Generally bone close by 16 to 18 years and you stop growing. Get your X-ray for bone age
and we would decide any possibility of growth is there or not. If your bone ends have closed, then the only possibilty would be to surgically lengthen your bones, which might not be advisable.
