Lipidated GLP-1 receptor agonist peptide of 31 residues
Research topic: Body & metabolism · group: GLP-1 class and amylin analogues
Semaglutide is a lipidated analogue of glucagon-like peptide-1 (GLP-1), 31 residues long, with a fatty-acid side chain attached through a linker. It is the active ingredient of approved medicines. What we supply is the same molecule, but not a medicine: lyophilized research material in vials, without the formulation, device or labelling of a finished drug. It opens the GLP-1 group of our body-composition and metabolic research page, followed by the dual and triple agonists. The studies in our product data reach from the medicinal-chemistry paper on its discovery to large cardiovascular-outcome trials.
Same molecule, not a medicine
Semaglutide is the active ingredient of approved medicines. What we supply is the same molecule, but not a medicine: lyophilized research material in vials, not a finished drug product.

Ask for the COA of the batch you are quoted; the batch number on it is the batch we ship.

What to put in your quote request
With these facts the first reply can carry the unit price per kit, shipping and lead time.
It is the same molecule — same sequence, side chain, formula and CAS. It is not a medicine: we supply it as lyophilized powder in vials for research, not as a finished, labelled drug product.
Because a lysine side chain carries a linker and a fatty acid. The formula and molecular weight in the fact table include them.
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.
