FAQ
What is Tirzepatide?
Tirzepatide is a synthetic 39-amino-acid peptide based on the native GIP sequence, modified with a C20 fatty diacid moiety attached via a linker to lysine at position 20, functioning as a dual GIP and GLP-1 receptor agonist. It is supplied globally in gram and kilogram quantities, available as bulk raw material or in vials with customizable aliquoting. The molecular formula is C225H348N48O68, with a molecular weight of 4813.53 g/mol and purity of at least 98% by HPLC.
In which supply forms can I order Tirzepatide?
Tirzepatide 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 Tirzepatide?
Raw Tirzepatide is supplied in quantities from 10 g to 1000 g. Available research vial specifications: 10 mg / 20 mg / 30 mg / 60 mg. Each kit contains 10 vials.
What is the minimum order quantity for Tirzepatide?
The minimum order for raw Tirzepatide is 10 g. For vial-packed Tirzepatide, the minimum order is 10 vials, equal to one kit.
In what physical form is Tirzepatide supplied and how is it packaged?
Raw Tirzepatide is supplied as lyophilized powder in fluorinated bottles, then vacuum packed in aluminum foil bags. Vial-packed research Tirzepatide is supplied as lyophilized powder in sealed pharmaceutical glass vials, with 10 vials per kit.
Is Tirzepatide in stock and what is the delivery time?
We keep kilogram-scale stocks of raw Tirzepatide, normally dispatching within 7 days. Research vials of Tirzepatide 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 Tirzepatide orders quoted and which wholesale discounts apply?
Raw Tirzepatide 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 Tirzepatide supplier?
LJH Global manufactures Tirzepatide raw material in-house and independently controls quality for consistent supply. Product purity: 99.8% (HPLC). Batch support includes COA, HPLC and LC-MS reports. Supply ranges from gram-scale raw material to custom milligram research vials for academic research and bulk procurement.
Where can I source Tirzepatide and request a bulk quotation?
Source Tirzepatide from China-based supplier LJH Global. Request current bulk pricing through our website inquiry form or WhatsApp. We reply within half an hour during working hours.
What are the structural features and mechanism of Tirzepatide?
Tirzepatide is a synthetic peptide consisting of 39 amino acids, structurally based on the native glucose-dependent insulinotropic peptide (GIP) sequence. It is chemically modified by attaching a C20 fatty diacid moiety via a linker to the lysine residue at position 20. This modification contributes to its stability and binding affinity. Tirzepatide acts as a dual agonist of GIP and GLP-1 receptors, engaging both receptor types.
What are the main research areas for Tirzepatide?
Research and development involving Tirzepatide includes supplier screening, quality document review, import and distribution preparation, process development, analytical method development, registration research, impurity research, and quality standard development. The supply chain and manufacturing capacity are critical due to the peptide's complexity and demand in pharmaceutical applications. Analytical techniques such as HPLC, LC-MS, peptide mapping, and impurity assignment are important for quality control and regulatory compliance.
Is Tirzepatide for human or veterinary use?
No. Tirzepatide 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.
