Semaglutide is a synthetic 31-amino-acid analogue of glucagon-like peptide-1 (GLP-1), the incretin that intestinal L-cells release after a meal. Two engineered features set it apart from the native hormone: an alpha-aminoisobutyric acid near the N-terminus that greatly reduces cleavage by dipeptidyl peptidase-4, and a gamma-glutamyl linker on a lysine carrying a C18 fatty diacid, which promotes reversible binding to albumin. In published pharmacokinetic studies these changes stretch its persistence in circulation from minutes to days.

That stability has made semaglutide one of the most cited tool compounds in incretin research. Labs use it to study GLP-1 receptor binding kinetics, cAMP accumulation and beta-arrestin recruitment in receptor-transfected cells, and downstream signalling in islet, hypothalamic and vagal-afferent preparations. It is also a standard positive control when new GLP-1, dual and triple agonists are profiled head to head.

Questions about Semaglutide

How pure is the semaglutide, and is the COA available?

At least 99% by HPLC for every lot, with mass spectrometry confirming identity. The lot's certificate is available on request and refers to the precise vial number you receive, making results traceable to your delivery.

Which vial sizes do you offer?

5 mg, 10 mg, 20 mg, 30 mg and 50 mg lyophilised vials. Bigger vials cost less per milligram, which helps longer assay programmes; smaller ones shorten how long a reconstituted stock has to wait in the fridge.

What is the correct storage?

Unopened lyophilised vials: −20 °C, away from light and humidity. After reconstitution: 2–8 °C, used within your documented study period. Make single-use aliquots so the stock isn't frozen and thawed over and over.

How does semaglutide compare with tirzepatide and retatrutide?

Semaglutide activates only the GLP-1 receptor. Tirzepatide acts on both GIP and GLP-1 receptors, and retatrutide adds glucagon-receptor activity on top. Labs often test all three together to compare receptor selectivity and downstream signalling.

Which solvent is used to reconstitute it?

Research labs typically use bacteriostatic water, or dilute alkaline or phosphate buffers when an assay needs a particular pH. Add the solvent slowly, swirl instead of shaking, and check the solution is clear before using it.
