Besides protective effects on substance use disorders, the authors analyzed the impact of GLP-1 receptor agonists on body weight management, body mass index (BMI), and glycated hemoglobin level (a measure of glycemic control)

Theoretical risks are extrapolated from IGF-1 biology: Hypoglycemia : IGF-1 shares structural homology with insulin and can activate insulin receptors, particularly at high concentrations Growth factor signaling : Sustained IGF-1R activation carries theoretical oncogenic potential, as the IGF-1 axis promotes cell proliferation and survival Systemic effects : Reduced IGFBP binding means greater systemic exposure to active growth factor, potentially amplifying both therapeutic and adverse effects Organ-specific : Potential for cardiac hypertrophy and other tissue growth with chronic exposure MGF Side Effects# MGF safety data are limited to preclinical observations: Rapid clearance : The very short half-life limits systemic exposure, which may reduce off-target effects Local action : Endogenous MGF acts primarily as a local paracrine factor, suggesting that targeted administration may have a favorable safety profile No human data : Without clinical trials, the safety profile in humans remains undefined Proliferative concerns : As a satellite cell activator, theoretical concerns exist regarding uncontrolled proliferation, though preclinical data have not demonstrated this Dosing and Administration Comparison# IGF-1 LR3 Dosing# MGF Dosing# The short half-life of native MGF is a significant practical limitation

In abdominal aorta anastomosis models, the peptide prevents and reverses thrombus formation, suggesting antithrombotic effects mediated through endothelial protection and normalized coagulation cascade activity

Under nutrient-replete conditions, the deacetylation of malonyl CoA decarboxylase (MCD) by SIRT4 plays a pivotal role in lipid homeostasis via suppressing fatty acid oxidation and inducing lipid anabolism
