It plays a role in improving insulin sensitivity, supporting glucose utilization, and enhancing metabolic efficiency at the cellular level

Researchers studying metabolic outcomes alongside body composition sometimes pair it with GLP-1 receptor agonist analogs compounds like Tirzepatide 10mg and Retatrutide 10mg represent a distinct class targeting metabolic pathways rather than the IGF-1 axis, making the mechanistic comparison instructive

However, secondary outcomes, such as ICU length of stay and mechanical ventilation duration, showed inconsistent results [35]
