"GH secretion in adults In healthy adults, it is known that fertile women have a higher GH secretion than young men (23) and that GH secretion is inversely associated with increasing age and adiposity (24, 25). These factors should be considered during GH replacement. Instead, GH dose schedules based on body weight or surface area results in higher daily doses of GH in subjects with higher body weight and lower for most women compared with men.
In middle-aged women, the reported daily production of GH is about 47 mg/L 3 24 h, whereas the mean production in the adult male is 15 mg/L 3 24 h. Assuming an availability of sc administered recombinant human GH of 60%, a dose between 0.3-0.6 mg (0.6-1.8 IU) per day should be in agreement with the physiological GH production in adults (26),
which is markedly lower than the doses of GH used in previous trials of GH replacement in adults."

1iu places me in the middle of the recommended range. I don't really care to argue, but it seems like the dosing advice given here is rather generous.

"The present study also examined 9 patients with childhood-onset GHD (aged 23–57 yr; 7 men and 2 women). Within 12 weeks of treatment, all nine and eight of nine patients reached normal levels of serum IGF-I and IGFBP-3, respectively. The dose of rhGH in this study group was 0.6 or 1.2 IU/day (mean doses, 1.0 IU/day; ;0.6 IU/m2zday;;0.11 IU/kg.week). Normalization of serum IGF-I was achieved with a mean dose of 1.0 IU/day, which is comparable with the dose advised by Wollmann et al. (12) but lowerthan the dose advised by Møller et al. (13) and De Boer et al.(14, 15). Wollmann et al. (12) examined 12 patients (9 men and 3 women) with childhood-onset GHD (20 –36 yr of age) in arandomized cross-over design with 3 treatment periods of 3months each (0.125, 0, 25, and 0.5 IU/kg BW.week)."
