Deficient synthesis of glutathione underlies oxidative stress in aging and can be corrected by dietary cysteine and glycine supplementation
(2007, Growth Hormone & IGF Research ) confirmed that following 300 eccentric lengthening contractions of the knee extensors in healthy young men, MGF mRNA expression peaked at 24 hours post-exercise while IGF-1Ea mRNA rose later at 72 hours providing direct in vivo human evidence of the sequential IGF-1 splice variant programme and establishing the temporal window for MGF-mediated satellite cell activation in physiological muscle damage

They found that the combination of these growth factors displayed a more significant maximum load and tensile stress and inhibited scar formation compared to the IGF-1 alone group, suggesting that combination of IGF-1 and TGF- is more effective than IGF-1 alone in the treatment of tendon injury ( Moreover, the efficacy of IGF-1 therapy can be influenced by factors such as age, health conditions, and injury type
It triggers a clean GH pulse with minimal effect on cortisol or prolactin
Contrarily, a study with 8 GH-deficient subjects found that IGF-1 administration increased lipid oxidation (being this effect more potent when co-administered with GH), energy expenditure, and insulin resistance [108, 183]
