GCG agonism provides direct hepatic effects by inhibiting lipogenesis and promoting fat oxidation while augmenting energy expenditure
Injectable semaglutide achieves roughly 89% bioavailability
Published research on glucagon-mediated energy expenditure shows that the thermogenic effect comes primarily from fat oxidation rather than protein catabolism, suggesting that the additional weight loss driven by glucagon receptor activation may be disproportionately fat mass
