This means semaglutide only stimulates insulin release when blood glucose is elevated
However: The meta-analysis did highlight some data showing that Tirzepatide demonstrated superior effectiveness over semaglutide [in reducing HbA1c levels]. In short, individual studies have shown some strong data backing tirzepatide as a more robust weight management drug than semaglutidebut the jurys still out, and we need to wait for more data overall
Hydration Status: While not a primary factor, extreme hydration could slightly dilute urine samples, potentially pushing concentrations below the detection limits of a less sensitive assay, though this is less likely with highly sensitive LC-MS/MS

Noguchi T, Katoh H, Nomura S, Okada K, Watanabe M (2024) The GLP-1 receptor agonist exenatide improves recovery from spinal cord injury by inducing macrophage polarization toward the M2 phenotype
Although studies determining the structure of GLP-1 bound to the N-terminal, extracellular domain of the receptor showed that the residues 13-33 of the GLP-1 peptide analogs form a helical structure (PDB ID 3iol, Underwood et al., 2010), recent EM structures of the whole receptor bound to the GLP-1 protein (PDB ID 6x18, Zhang et al., 2020) shows that the entire GLP-1 peptide forms a long helix as it binds to its receptor
