15. The method of claim 14 , wherein said IGF-1 is administered subcutaneously.
16. A method for achieving at least normal insulin-like growth factor-1 (IGF-1) levels for age and gender in a human subject having insulin-like growth factor-1 deficiency (IGFD), comprising
administering an effective amount of insulin-like growth factor (IGF-1) to the human subject, wherein the human subject is characterized as follows:
at the time of treatment or prior to initial treatment with IGF-1, has or had a height at least about 2 standard deviations (SD) below a normal mean for a human subject of the same age and gender, and
at the time of treatment or prior to initial treatment with IGF-1, has or had a blood level of IGF-1 at least about −1 SD below normal mean levels for a human subject of the same age and gender,
wherein the human subject does not have Laron syndrome or partial growth hormone insensitivity syndrome, and wherein said administering achieves normal blood IGF-1 levels for age and gender in the human subject.
