Because in the absence of suggestive clinical circumstances there is a significant false-positive error rate in the response to a single GH stimulation test, we suggest the use of two tests before making this diagnosis. "GH replacement therapy can provide a number of measurable benefits to GH-deficient adults. These include improved bone density, increased muscle mass, decrease of adipose tissue, faster hair and nail growth, strengthened immune system, increased circulatory system, and improved blood lipid levels, but long term mortality benefit has not yet been demonstrated.A peer-reviewed article published in 2010 indicates that "Growth hormone (GH) replacement unequivocally benefits growth, body composition, cardiovascular risk factors and quality of life. Less is known about the effects of GH on learning and memory." Other
As of 2004, GH has been approved by the U.S. Food and Drug Administration for treatment of other conditions such as:

In adults, wasting (or cachexia) caused by AIDS. Turner syndrome epitomizes the response of non-deficient shortness. At doses 20% higher than those used in GH deficiency, growth accelerates. With several years of treatment the median gain in adult height is about 2–3 in (5.1–7.6 cm) on this dose. The gains appear to be dose-dependent. It has been used successfully in toddlers with Turner syndrome, as well as in older girls. Short-stature homeobox gene deficiency 
Chronic kidney failure results in many problems, including growth failure.
