Dual GLP-1 and glucagon receptor agonist peptide (IBI362 / LY3305677)
Research topic: Body & metabolism · group: GLP-1 class and amylin analogues
Mazdutide, development codes IBI362 and LY3305677, is a synthetic peptide related to oxyntomodulin that activates the GLP-1 and glucagon receptors and carries a long-chain fatty-diacid side chain. Public databases do not all draw its structure the same way, which makes the lot documents — sequence, linker and mass on the COA — the reference for identity. The same molecule has been approved as a medicine in China; what we supply is that molecule as research material in vials, not a medicine. It belongs to the GLP-1 group of our body-composition and metabolic page.
Same molecule, not a medicine
The same molecule has been approved as a medicine in China. What we supply is research material in vials — the same molecule, but not a medicine.

Ask for the COA of the batch you are quoted; the batch number on it is the batch we ship.
Each picture is the first page at low resolution, with numbers, dates and signatures covered, so the small print cannot be read. The full, clear copy comes from sales — ask for it by product and strength.

What to put in your quote request
With these facts the first reply can carry the unit price per kit, shipping and lead time.
Both act on the GLP-1 and glucagon receptors, but they are different molecules with their own sequences, formulas and CAS numbers.
Public records draw the side chain and its linker in different ways, so their formulas differ. The fact table gives the formula of our product table, and the COA of the lot confirms the mass of the material supplied.
One kit is 10 vials of the same product at the same strength. Each vial holds the stated amount, for example 10 mg of lyophilized peptide; the few solutions are stated per vial in mg or ml. 1 kit per product and strength. One order can combine several products and strengths, each from 1 kit.
HPLC purity, MS identity, endotoxin and fill, on the COA of every lot of a stocked peptide. The COA carries the lot number, so you can match it to the vials you receive. Yes. Ask for the COA of the batch you are quoted; the batch number on that COA is the batch we ship.
In writing, per request. Prices are tiered by the number of kits of each peptide and strength; the quotation gives the unit price per kit, the shipping cost and the lead time. We reply within 24 hours.
Because listings describe different forms: a free peptide or a salt (acetate, TFA), a copper complex or its free peptide, one peptide or a two-peptide material — and some registries keep older numbers. Each product page says which form its values refer to; the COA of the lot is the reference. For Mazdutide: Public databases draw the side chain and linker differently; the formula shown is our product table's, and the lot COA confirms the mass.
