At a separate -arrestin recruitment pathway at GLP-1R, reta E_max = 40% of native (partial / biased agonism), tirzepatide partial in the same direction, semaglutide full at both pathways
On the other hand, GSH and 2-mercaptoethanol displayed similar potency, needing thiol:AX ratios above 4:1 to obtain a complete abolition of antibiotic effects ( Figures 6B, C )

The reta + cag stack swaps semaglutide for retatrutide - which already hits three receptors - aiming to layer amylin satiety on top of broader metabolic effects
