Retatrutide
glp1Retatrutide is a research-use-only peptide. PeptideSource compares suppliers on purity, COAs, and price-per-mg.
Also known as: Reta, LY3437943, GGG Tri-Agonist, GLP-3 RT, GLP-3(R), GLP3-R, GLP3R, GLP-3 R, 3G-RT, GLP-1R, GLP-1R (GLP3), GLP3, MA-3RT
Retatrutide acts by targeting and activating receptors for three hormones: GLP-1, GIP, and glucagon. This peptide, also known as LY3437943 or GGG Tri-Agonist, is a synthetic analog not found endogenously. Early research interest in Retatrutide emerged from the need to address multiple metabolic disorders simultaneously, leading to exploration of its multi-receptor approach. Today, it is primarily studied for its effects on:
- Metabolic syndrome
- Obesity management
- Type 2 diabetes
- Cardiovascular health
Its multi-functional capability has sparked interest in broader metabolic disorder treatments.
