The incretin class covers compounds that act at the GLP-1 receptor and, in the newer molecules, at the GIP and glucagon receptors alongside it. The published research on this group is unusually deep for a research-peptide category: semaglutide and tirzepatide both carry large named clinical programmes, and retatrutide — a triple agonist — has phase 2 data in the literature under its own compound code.
This category groups the single, dual and triple receptor agonists together with the amylin analogues, because the research questions overlap. Cagrilintide and eloralintide are studied at the amylin receptor rather than the incretin receptors, and appear here for that reason. Orforglipron sits in the same collection despite being a non-peptide small molecule, since it is characterised as an orally available GLP-1 receptor agonist.
Every lot in this category is independently assayed before it is released. The batch identifier, the measured purity and the measured content are printed on the product card and on the certificate itself, so the numbers are visible before anything is added to a cart rather than after delivery. All compounds are supplied strictly as laboratory research materials.
