MOLECULAR PROFILE

What Is GLP-3?

GLP-3 (LY3437943) is a 39-amino-acid synthetic peptide engineered for balanced agonism at the gastric inhibitory polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon receptors. Vorix Labs supplies GLP-3 as a research catalog item with Janoshik Analytical batch CoA documentation and USA warehouse fulfillment. Laboratory / in-vitro use only — not for human or veterinary use.

GLP-3 (LY3437943) is a 39-amino-acid synthetic peptide engineered for balanced agonism at the gastric inhibitory polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon receptors. Characterized in preclinical and clinical research literature exploring integrated multi-receptor signaling.

Researchers searching for GLP-3, Retatrutide, or LY3437943 typically need a documented triple-agonist reagent for metabolic and incretin-pathway assays. Vorix Labs supplies lyophilized GLP-3 with batch-level identity testing so protocols can cite purity and lot data. Common lab search terms this page targets include “buy Retatrutide research peptide,” “GLP-3 for sale,” and “LY3437943 CoA.” Material is intended strictly for controlled laboratory use — not for clinical or consumer applications.

FAQ

GLP-3 — common research questions

Straight answers for researchers comparing purity, CoA documentation, kits, and shipping.

Is GLP-3 for research use only?

Yes. GLP-3 from Vorix Labs is sold strictly for laboratory / in vitro research. It is not for human or veterinary use and is not evaluated by the U.S. FDA for any clinical purpose.

Do you provide a Certificate of Analysis for GLP-3?

Every Vorix batch is identity-verified with a Janoshik Analytical Certificate of Analysis (CoA). CoA access is available on the product page and through our CoA library for researchers who need batch documentation.

Can I buy GLP-3 as a single vial or a kit of 10?

Yes. Most catalog SKUs offer a single vial and a kit-of-10 option with kit pricing when inventory supports a full kit. Select the package size on the product page before adding to cart.

Where does Vorix Labs ship GLP-3 from?

Orders ship from our USA warehouse with domestic fulfillment. Standard shipping is free on qualifying orders of $250+.

Is GLP-3 the same as Retatrutide?

GLP-3 is the catalog name Vorix uses for the research peptide commonly referenced as Retatrutide (LY3437943) — a 39-residue multi-receptor agonist studied in published metabolic research literature.
