What is Retatrutide?
Retatrutide is a synthetically produced 39-amino-acid peptide belonging to the new class of triple-agonists. Unlike classic mono-agonists (e.g. Semaglutide – GLP-1 only) or dual-agonists (e.g. Tirzepatide – GLP-1/GIP), Retatrutide simultaneously activates three receptor types: the Glucagon-like Peptide-1 receptor (GLP-1R), the Glucose-dependent Insulinotropic Polypeptide receptor (GIPR) and the Glucagon receptor (GcgR). In preclinical models, this triple affinity enables the study of synergistic signaling cascades that cannot be replicated with single- or dual-receptor binders. At NovaCell, Retatrutide is offered under the brand name Nova Triple G strictly as a research peptide (RUO).

cAMP signaling, incretin system, insulin secretion in vitro.
Glucose-dependent Insulinotropic Polypeptide receptor
Adipocyte function, lipid metabolism, β-cell research.
Glucagon receptor
Hepatic gluconeogenesis, energy homeostasis models.

Retatrutide, Reta, Nova Triple G – three names, one molecule
All three names refer to the same substance. Reta is the short form used in laboratories and research forums, Nova Triple G is our product name for the reference material, and LY3437943 is the research code assigned during development. Whichever spelling you search for, you end up with the same 39-amino-acid peptide acting at GLP-1, GIP and glucagon receptors.
The material is supplied as lyophilized powder in four vial sizes: 10, 20, 30 and 60 mg. Every batch ships with its own certificate of analysis (COA) documenting purity by HPLC and identity by LC-MS. All sizes are intended strictly for research purposes (Research Use Only).

Retatrutide (GLP-3) — triple-agonist reference molecule
Retatrutide, labeled as Nova Triple G in our range, is a synthetic triple-agonist peptide that binds simultaneously to three metabolic receptors: GLP-1R, GIPR and the glucagon receptor. As the most potent molecule in this class to date, it serves as the preclinical reference for triple-agonist vs mono/dual comparisons.
The NovaCell 10mg batch ships lyophilized with full COA (HPLC + LC-MS) and ≥99% purity. For receptor-binding, cAMP signaling and pharmacokinetic studies, Retatrutide is the current reference substance for triple incretin research.

Crypto payment is complicated for beginners. Nova Triple G is very good though.
Retatrutide (Nova Triple G) – an overview for research
Retatrutide (development name LY3437943) is a synthetic peptide that acts as a triple agonist at three receptors: the GIP receptor, the GLP-1 receptor and the glucagon receptor. This sets it apart from dual agonists, which address only two of them. In research it is used in in-vitro studies of incretin and glucagon receptor signalling. NovaCell supplies it strictly for research purposes (Research Use Only).
At NovaCell, retatrutide is offered as Nova Triple G, strictly for research purposes (Research Use Only), in 10, 20 and 30 mg vials. Our newer research compound GLP5 is listed separately in the catalogue.
