Why IGF-1 Labs Don't Tell the Whole Story in Hormone Optimization
IGF-1 is a helpful marker, but it fluctuates daily with sleep, nutrition, stress and timing—so a single lab value rarely captures true growth hormone status.
Receptor sensitivity declines with age, meaning normal lab results don’t always reflect adequate biological effect.
Prioritize symptoms—low energy, poor recovery, stubborn fat, and disrupted sleep—alongside labs when assessing hormone health.
Begin with lifestyle optimization (nutrition, sleep, stress management). When appropriate, consider targeted peptides such as tesamorelin or ipamorelin to support hormonal balance.
