Overview
About GLP3-RT 10mg
GLP3-RT 10mg is a high-purity synthetic peptide corresponding to retatrutide (research designation LY3437943), supplied by Echo Peptides exclusively for laboratory and in-vitro research use. It is a single-molecule triple agonist engineered to engage three metabolic receptors at once — the glucose-dependent insulinotropic polypeptide (GIP) receptor, the glucagon-like peptide-1 (GLP-1) receptor, and the glucagon receptor.
As a research reference compound, GLP3-RT is valued for the way its unified structure lets investigators probe converging incretin and glucagon signaling within a single molecular framework rather than combining separate agonists. Its fatty-acid conjugate and targeted structural modifications are designed to improve stability in cell-culture and preclinical model systems, making it a useful tool for researchers studying multi-receptor metabolic pathways.
Key research areas
Multi-receptor metabolic and energy-expenditure models
Glucose homeostasis and appetite-regulation signaling pathways
Lipid metabolism and body-weight-related research paradigms
Combined incretin and glucagon receptor signaling in preclinical and in-vitro systems

Working with the 10mg vial
This vial contains 10 mg of lyophilized material. Reconstitution does not change that mass — it changes the volume it occupies — so the concentration you end up with is set entirely by how much diluent you add.

Frequently Asked Questions
What is GLP3-RT 10mg?
GLP3-RT 10mg is a high-purity synthetic peptide corresponding to retatrutide (research designation LY3437943). It is a single-molecule triple agonist that engages the GIP, GLP-1, and glucagon receptors, and it is supplied by Echo Peptides for in-vitro laboratory research use only.
What do laboratories study GLP3-RT for?
Researchers use GLP3-RT as a reference compound in cell-culture and preclinical models exploring multi-receptor metabolic signaling, glucose homeostasis, appetite-regulation pathways, and lipid metabolism. Its unified triple-agonist structure lets labs examine converging incretin and glucagon pathways within a single molecule.
How is GLP3-RT 10mg supplied, tested, and stored?
It ships as a 10mg lyophilized white powder that is soluble in bacteriostatic water for research use. Each batch is third-party tested for identity and purity with a Certificate of Analysis available. Refrigerate at 2–8°C; the lyophilized powder offers long-term stability.
