Published research has reported the following reference ranges: Preclinical (rodent) models: doses in the range of 0.13 nmol/kg administered at periodic intervals to evaluate pharmacokinetics, receptor activation, and metabolic signaling responses Early-phase clinical investigations: escalating dose protocols beginning at sub-milligram weekly doses, as reported in Phase 1 and Phase 2 trial literature (Coskun et al., 2022) In vitro systems: receptor binding and activation studies conducted at nanomolar concentrations to evaluate GLP-1R, GIPR, and GCGR engagement These values are model- and protocol-specific and do not translate directly to human use
