Not really. They speculate why critically ill patients with burns, trauma, sepsis (with nutritional and hormonal deficiencies, an out of whack immune system, etc.) have lower IGF production. None of that is relevant for how PEDs and other elements of bodybuilding lifestyle affect IGF1 production. Things like insufficient estrogenic activity, liver damage from orals, deficiencies of particular nutrients (e.g VitD) are what causes subpar IGF1 response in bodybuilders, and none of those factors are specifically discussed in the article.
