2x Retatrutide 20 mg Bundle
For in-vitro laboratory research use only. Not intended for human consumption, veterinary, diagnostic, or clinical use.
Description
This bundle brings together 2× Retatrutide 20 mg in a single research bundle, priced around 15% below buying each vial separately. Each peptide is supplied in its own individual vial, so reconstitution and handling stay fully independent per compound.
Every vial is lyophilized research-grade powder at ≥ 99% HPLC purity, with a Certificate of Analysis available on request.
For laboratory research use only. Not for human or veterinary use.
Retatrutide 20 mg
This 20 mg vial of Retatrutide is supplied as a higher-content format for reduced-reconstitution-frequency research applications. Retatrutide 20mg peptide is a synthetic 39-residue triagonist designed to engage three incretin and metabolic-pathway receptors simultaneously: the glucose-dependent insulinotropic polypeptide (GIP) receptor, the glucagon-like peptide-1 (GLP-1) receptor, and the glucagon receptor. By combining activity across these three receptor systems within a single molecule, retatrutide is investigated as a research compound for studying coordinated incretin-pathway research, insulin-signaling crosstalk, and energy-metabolism research in controlled laboratory settings.
Research interest in Retatrutide 20mg peptide has focused on how triple-receptor engagement may modulate downstream metabolic-pathway research models beyond what is observed with single- or dual-agonist incretin compounds. Mechanistic data indicate that retatrutide engages GIP, GLP-1, and glucagon receptors with distinct intrinsic activity profiles, supporting investigations into combined receptor signaling, energy-expenditure pathways, and metabolic-pathway adaptation in research models (Coskun et al., 2022, Cell Metabolism; Jastreboff et al., 2023, New England Journal of Medicine).
Beyond incretin-pathway research, Retatrutide 20mg peptide has also been investigated in laboratory research studies examining hepatic lipid-metabolism research models, glucose-signaling markers, and cardiometabolic-pathway research. These investigations have positioned retatrutide as an experimental research compound of interest in studies of triagonist receptor pharmacology and integrated metabolic-pathway signaling.

Scientific Background
2x Retatrutide 20 mg Bundle combines 1 research compounds: Retatrutide 20 mg. Scientific background for each component is documented below.
Retatrutide 20 mg
Retatrutide (also referenced in research literature as LY3437943) is a synthetic 39-residue peptide engineered as a unimolecular triagonist of the GIP, GLP-1, and glucagon receptors. It was developed to extend the pharmacology of earlier incretin-based research compounds, including single-agonist GLP-1 analogs and dual GIP/GLP-1 agonists, by adding a third receptor arm: glucagon receptor engagement.
The rationale behind triagonist research is that combined receptor signaling may modulate energy-metabolism research models through complementary pathways. GLP-1 receptor activity contributes to glucose-signaling research and central neuroendocrine-pathway research; GIP receptor activity is associated with insulin-signaling research and lipid-pathway adaptation in adipose research models; glucagon receptor activity is investigated for its association with energy-expenditure research and hepatic lipid-metabolism research.
This positioning at the intersection of three established incretin and metabolic-pathway receptors has made retatrutide an experimental research compound of considerable interest in laboratory research studies of integrated receptor pharmacology, metabolic-pathway crosstalk, and energy-balance research models.

Mechanism of Action
Each compound in 2x Retatrutide 20 mg Bundle engages distinct biochemical targets. Mechanism of action per compound:
Retatrutide 20 mg
1. GLP-1 Receptor Engagement
Retatrutide engages the GLP-1 receptor, a class B G-protein-coupled receptor expressed across pancreatic, central, and peripheral tissues in research models. GLP-1 receptor signaling research is associated with glucose-dependent insulin-signaling pathways and central neuroendocrine modulation relevant to energy-balance research.
2. GIP Receptor Engagement
Retatrutide also engages the GIP receptor, which is widely expressed in adipose and pancreatic research tissues. GIP receptor signaling is investigated for its role in insulin-signaling research, adipose-pathway adaptation, and lipid-handling research models.
3. Glucagon Receptor Engagement
The glucagon receptor arm distinguishes retatrutide from dual-agonist research compounds. Glucagon receptor signaling is investigated in laboratory research studies for its association with hepatic glucose-output research, lipid-metabolism research, and energy-expenditure research models.
4. Integrated Triagonist Signaling
By interacting with all three receptor systems within a single molecule, retatrutide is investigated as a tool for studying receptor-balance pharmacology, downstream signaling crosstalk, and integrated metabolic-pathway adaptation in research models. Preclinical and laboratory research has characterized its balanced GCGR/GLP-1R activity with relatively higher GIPR activity (Coskun et al., 2022, Cell Metabolism).
Research Applications
Conclusion
Retatrutide represents an experimental research compound class of unimolecular triagonists that engage GIP, GLP-1, and glucagon receptors simultaneously. By integrating three receptor arms within a single peptide, retatrutide supports laboratory research studies of receptor-balance pharmacology and integrated metabolic-pathway signaling, making it a valuable research target for investigations of incretin-pathway research and energy-metabolism research models.
