Is NAD+ actually a peptide

Tirzepatide Dual agonist : GLP-1 + GIP Central benchmark for dual incretin research Often discussed in relation to body-weight outcomes, glycaemic control and incretin signalling Single agonist : GLP-1 More selective and mechanistically narrower Common reference point for GLP-1 pathway research Triple agonist : GLP-1 + GIP + glucagon Broader receptor profile than Tirzepatide Often discussed in relation to weight loss, energy expenditure and next-generation multi-pathway metabolic modulation For researchers comparing incretin classes, Tirzepatide often functions as the middle reference point between single-pathway GLP-1 agonists and broader triple-agonist designs
