02How They Differ
Semaglutide
A long-acting GLP-1 receptor agonist studied for incretin signaling and glucose-metabolism research.
Semaglutide is a long-acting synthetic analog of glucagon-like peptide-1, acting as an agonist of the GLP-1 receptor. Research models study its role in incretin signaling, glucose-dependent insulin secretion, and energy-homeostasis pathways.
Cagrilintide
A long-acting amylin analog studied for amylin-receptor signaling and satiety-pathway research.
Cagrilintide is a long-acting synthetic analog of the hormone amylin, studied for agonism at the amylin and calcitonin receptor family. Research models examine its role in satiety signaling, gastric-emptying, and energy-balance pathways.

03Selecting for a Research Model
Because Semaglutide and Cagrilintide are both metabolic research compounds, they are frequently evaluated against one another. Selection depends entirely on the research question, model system, and endpoints being measured. Both compounds are supplied strictly for in-vitro and laboratory research and are not for human or veterinary use.
Whichever you select, every Ethos Bio lot is verified the same way — a five-point independent panel with a batch-specific Certificate of Analysis. See how we test →
