Growth hormone secretion rises through childhood and doubles or more at puberty under oestrogen and testosterone, both of which act centrally. Oestrogen, from either sex, is the main driver of the pubertal growth spurt and of growth plate fusion that ends it. Nutrition modulates the whole curve: undernutrition lowers IGF-1 at every age.
The adolescent peak is the highest IGF-1 exposure of a normal lifetime.
A level normal for a fourteen-year-old would indicate acromegaly in a sixty-year-old and might indicate deficiency in a ten-year-old at a late pubertal stage. Laboratories report ranges by age and sex; the pubertal stage is added clinically. The 2011 consensus called for ranges derived from large, well-characterised populations for this reason.
Bone age is sometimes used instead of chronological age for the comparison.
Because the physiology of the molecule over a lifetime is part of what is established about it, and because the pubertal peak is the natural upper bound against which the longevity and cancer literatures implicitly compare. It describes no use of the pack.
