About GLP class research compounds

GLP class compounds are synthetic peptides designed to bind incretin receptors, the G protein coupled receptors for GLP-1 and GIP, and in some designs the related glucagon receptor. Tirzepatide is a dual agonist that activates GIP and GLP-1 receptors. Retatrutide is a triple agonist that adds glucagon receptor activity, which makes it useful for comparing single, dual and triple receptor signaling in cell based assays. Both are supplied as lyophilized powder and are reconstituted before in vitro work. For background, read our GLP receptor agonist research overview, the retatrutide compound profile and the GLP family overview, then plan concentrations with the peptide reconstitution calculator.

Choosing a vial size

Larger vials cost less per milligram, so compare price per mg below before choosing a size for your study.

GLP Research Peptides FAQ

What is the difference between tirzepatide and retatrutide?
Tirzepatide is a dual receptor agonist acting on GIP and GLP-1 receptors. Retatrutide is a triple receptor agonist that also acts on the glucagon receptor. See the retatrutide compound profile for details.
How should GLP class vials be stored?
Keep sealed lyophilized vials cold, dry and away from light, and follow the notes in our storage and handling guide.
Are these products for human use?
No. These products are sold for research use only to buyers 18 or older and are not for human or veterinary use.
