The skin is cleaned with an antiseptic wipe at the injection site, usually the upper outer arm, and the intramuscular injection is given with a fine needle in around ten seconds

GLP-1 Receptor Activation Metabolic Regulation GLP2 activates GLP-1 receptors with lower potency than endogenous GLP-1 but demonstrates biased signaling properties: Preferential cAMP pathway activation over beta-arrestin recruitment, which may enhance insulin secretory responses Suppression of inappropriately elevated glucagon secretion during hyperglycemia Reduced GLP-1 receptor internalization compared to native GLP-1, potentially extending signaling duration Contribution to glucose-dependent insulin secretion complementary to GIP receptor effects Research in isolated pancreatic islets demonstrated that GLP2s insulinotropic actions depend on GIP receptor presence, with the biased GLP-1 receptor signaling providing synergistic enhancement

They were also found to activate the PI3K/Akt pathway, which promotes cell survival and reduces apoptosis in neuronal cells exposed to OS (Bakhtiari et al., 2017
