About this group
These are the compounds most often ordered for metabolic, appetite-signalling and energy-balance research models. Incretin agonists in this group act at GLP-1, GIP and glucagon receptors to varying degrees, which is what separates a single, dual and triple agonist from one another. This group is also what people are looking for when they search for peptides for weight loss. That phrase describes an outcome measured in supervised clinical trials of licensed medicines, which is not what research-grade material is: nothing here is licensed, none of it is supplied for human use, and no page on this site gives dosing or administration guidance. What the group actually contains is incretin receptor agonists studied in metabolic and appetite-signalling models. Every item ships in a box of 10 vials with a batch-specific Certificate of Analysis.
