Female on Placebo
Participants received placebo. Placebo Growth Hormone : Participants gave themselves injections of placebo every night for 6 months.
Male on GH
Participants received growth hormone replacement therapy. The starting dose was 2 micrograms/kg per day and they were titrated within the normal range based on blood levels. Nutropin AQ growth hormone : Participants gave themselves injections of growth hormone every night for 6 months.
