GLP Analog Research Peptides
Synthetic incretin-receptor agonist peptides for laboratory research. Research use only.
About the GLP analog peptides
This section lists synthetic peptides that act at incretin-family receptors. GLP-1 SM is the catalog name for semaglutide, a GLP-1 receptor agonist; GLP-2 TZ is tirzepatide, a dual GIP and GLP-1 receptor agonist; GLP-3 RT is retatrutide, which acts at the GIP, GLP-1 and glucagon receptors. PT-141, a melanocortin-receptor peptide, is also listed here.
Each compound is supplied as a lyophilized powder in a sealed vial. Batch COAs are published in our COA library, and each product page lists the compound's sequence or structure, molecular weight and storage guidance. Our comparison pages set the compounds side by side by structure and receptor targets.
All products in this section are sold for laboratory research use only. They are not for human or animal use, and nothing on this page describes dosing or use in the body.
Frequently asked questions
What is the difference between GLP-1 SM, GLP-2 TZ and GLP-3 RT?
They act at different receptor sets: GLP-1 SM (semaglutide) at the GLP-1 receptor, GLP-2 TZ (tirzepatide) at the GIP and GLP-1 receptors, and GLP-3 RT (retatrutide) at the GIP, GLP-1 and glucagon receptors.
How are these compounds supplied and stored?
As a lyophilized powder in a sealed vial. Keep vials cool, dry and away from light; 2-8 °C, or -20 °C for longer storage. Once reconstituted with bacteriostatic water, keep the solution refrigerated.
Are these products for human use?
No. Every product in this section is sold strictly for in-vitro laboratory research. They are not for human or animal use, and we do not provide dosing information.
Research use only. Products in this category are sold for laboratory research and are not for human or animal use. See the COA library for certificates of analysis and Compare for side-by-side research notes.
