Beta-3 adrenergic receptor expression begins increasing in adipose tissue, and the baseline rate of lipolysis elevates
But the medications which include those sold under brand names Ozempic, Wegovy, Mounjaro and Zepbound can come with some uncomfortable and potentially risky side effects, including nausea, diarrhea, vomiting, constipation and dehydration, as well as bone and muscle loss
Under this condition, GLP-1 and GIP both activate Gs and increase cAMP production, thereby amplifying insulin secretion through PKA- and Epac2-dependent pathways (63, 64) (Figure 8B)

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
