Buy Semaglutide peptide as lyophilised powder in sealed vials of 2 mg, 5 mg, 10 mg or 15 mg. Semaglutide is a synthetic analogue of human GLP-1 with 31 amino acids and a fatty diacid side chain. In laboratories it is a common reference compound for GLP-1 receptor assays. The product on this page is a research chemical, not a medicine.

Buy Semaglutide: vial sizes and form

Semaglutide is supplied in four vial sizes. The 2 mg and 5 mg vials cover single receptor assays and method tests, the 10 mg and 15 mg vials are intended for series. Every vial contains lyophilised powder under a sealed cap, with the amount and the lot number printed on the label. Laboratories that compare receptor profiles usually run Semaglutide next to Tirzepatide (GLP-1 and GIP) and Retatrutide (GLP-1, GIP and glucagon). All three are listed under GLP-1 and metabolic research peptides.

What Semaglutide is: a GLP-1 analogue with 31 amino acids

Human GLP-1 is broken down within minutes. Semaglutide keeps the GLP-1 sequence but replaces two amino acids and carries a fatty diacid chain that binds to albumin. These changes make the molecule far more stable in assays than the natural hormone. For analytics this means a defined mass of about 4,114 Da that is easy to confirm by mass spectrometry.

Questions about Semaglutide

Is Semaglutide a peptide?

Yes. Semaglutide is a peptide of 31 amino acids, a modified analogue of the human hormone GLP-1. The fatty diacid side chain is attached to one of the amino acids.

Is the Semaglutide in this shop a medicine?

No. Medicines with this active substance exist, but the product on this page is a research chemical for laboratory use. It is not a medicine and we give no information on use in humans.
