HGH therapy involves subcutaneous injections with a very small needle, typically in the abdomen, thighs or buttocks. Injections are self-administered 1-2 times per day, often before bedtime when natural HGH production peaks. The initial dose is low, typically not more than 1-3 IU (international units) per day, split into smaller doses. Doses may be gradually titrated up based on lab work, medical assessment, and patient tolerance. Treatment is supervised by an endocrinologist or anti-aging specialist and lab work is needed periodically to monitor hormone, blood sugar, and lipid levels.
