FAQ

What is Retatrutide?
Retatrutide is a chemically modified synthetic peptide supplied as an API for research and development, quality evaluation, and import/distribution preparation. It is a long-chain peptide with molecular formula C221H342N46O68 and molecular weight 4731.4 g/mol. Retatrutide is an investigational molecule in clinical development as a triple receptor agonist targeting GIP, GLP-1, and glucagon receptors, currently evaluated in multiple Phase 3 clinical programs. Supply is intended for qualified pharmaceutical companies, research institutions, CDMOs, and other B2B organizations, with available documentation including COA, HPLC, LC-MS, peptide content, batch information, packaging, and storage details. Retatrutide API is not for personal use or direct consumer sale.
In which supply forms can I order Retatrutide?
Retatrutide is available as bulk raw material and vial-packed research material. Specify the required supply form when requesting a quotation.
Which raw material and vial specifications are available for Retatrutide?
Raw Retatrutide is supplied in quantities from 10 g to 1000 g. Available research vial specifications: 10 mg / 20 mg / 30 mg / 50 mg / 60 mg. Each kit contains 10 vials.
What is the minimum order quantity for Retatrutide?
The minimum order for raw Retatrutide is 10 g. For vial-packed Retatrutide, the minimum order is 10 vials, equal to one kit.
In what physical form is Retatrutide supplied and how is it packaged?
Raw Retatrutide is supplied as lyophilized powder in fluorinated bottles, then vacuum packed in aluminum foil bags. Vial-packed research Retatrutide is supplied as lyophilized powder in sealed pharmaceutical glass vials, with 10 vials per kit.
Is Retatrutide in stock and what is the delivery time?
We keep kilogram-scale stocks of raw Retatrutide, normally dispatching within 7 days. Research vials of Retatrutide are kept in stock, normally delivered within 7 days. If stock cannot cover your order, we arrange production, usually taking 7 days, with delivery in 7–15 days.
How are bulk Retatrutide orders quoted and which wholesale discounts apply?
Raw Retatrutide is quoted at gram and kilogram scales. Bulk research-vial orders qualify for wholesale discounts when they reach the applicable order amount. Every first order receives wholesale pricing regardless of its amount, reducing first-order evaluation costs. Quotes reflect specification, quantity, packaging and delivery destination.
Why choose LJH Global as your Retatrutide supplier?
LJH Global manufactures Retatrutide raw material in-house and independently controls quality for consistent supply. Product purity: 99.8%. Batch support includes COA, HPLC and LC-MS reports.

What are the structural features and mechanism of Retatrutide?
Retatrutide is a long, chemically modified synthetic peptide with the sequence YX-Aib-EGTFTSDYSIYLDKKAQX-Aib-EFVQWLLAGGPSSGAPPPS-Lys(γGlu-2xOEG-C18 diacid)-NH₂. It acts as a single-molecule triple receptor agonist targeting the GIP, GLP-1, and glucagon receptors. The peptide includes modifications such as Aib residues and lipidation with a γGlu-2xOEG-C18 diacid moiety. Its mechanism involves activation of these receptors, but detailed pharmacological or clinical mechanism data are not provided in the sources.
What are the main research areas for Retatrutide?
Research on Retatrutide API focuses on clinical development, process development, quality research, impurity profiling, analytical method development, and pre-registration studies. It is involved in multiple Phase 3 clinical trials with thousands of participants. The supply chain emphasizes peptide API process research, custom synthesis of intermediates and fragments, impurity reference materials, and CDMO services. Analytical evaluation includes impurity profiling, batch consistency, peptide content determination, and structural confirmation using HPLC, LC-MS, amino acid analysis, and other orthogonal methods. The China supply chain offers advantages in peptide synthesis, purification, process scale-up, and quality documentation for Retatrutide API.
Is Retatrutide for human or veterinary use?
No. Retatrutide is supplied only as a chemical reagent for in-vitro laboratory research, not for human or veterinary use. LJH Global is not a pharmacy or compounding facility.
