From a lizard-venom discovery in the 1990s to the most studied molecules in metabolic science. Here is what the published research actually shows, and where the field is heading next.
Hydration, elasticity, wrinkle depth. A plain reading of the trial data, the meta-analyses, and the funding question that changes how the results look.
Dual agonist against single agonist. What the SURPASS, SURMOUNT, and STEP trial programs measured, and how the two molecules differ at the receptor level.
