Semaglutide

Semaglutide is a long-acting GLP-1 receptor agonist built on a 31-amino-acid backbone. Available in 10 mg, 20 mg and 30 mg lyophilised vials.

A C18 fatty-acid chain at position 26 drives albumin binding, and an Aib substitution at position 8 blocks DPP-4 cleavage, which together give the molecule a circulating half-life measured in days rather than minutes. That stability is the reason it appears so often in incretin research: a single administration holds receptor occupancy long enough to study sustained signalling rather than a short pulse.

Supplied as a lyophilised powder per vial, sealed under vacuum. Store the sealed vial at -20 C, reconstitute with bacteriostatic water, and keep the reconstituted solution refrigerated and out of direct light.

Avoid repeated freeze-thaw cycles, which are the most common cause of measurable potency loss. Researchers comparing incretin classes usually run it against tirzepatide and retatrutide.
