Semaglutide Research Hub

Semaglutide is a long-acting GLP-1 receptor agonist: a GLP-1 analog with two amino-acid substitutions and a C18 fatty diacid chain at lysine 26 that binds albumin (CAS 910463-68-2, about 4113.6 Da).

Semaglutide is a single agonist of the GLP-1 receptor. Tirzepatide adds GIP-receptor activity, and retatrutide adds both GIP and glucagon-receptor activity. Semaglutide is therefore the standard single-receptor comparator in incretin research.

Research areas include incretin signalling, glucose handling, appetite pathways, and comparative studies against dual and triple agonists. It is the most widely studied GLP-1 analog in current metabolic research.

QSC supplies 5, 10, 15, 20, 30, 40 and 50 mg vials. Choose by stock concentration and how quickly you will use the solution. Concentration equals the milligrams in the vial divided by the millilitres of solvent: a 10 mg vial in 5 mL gives 2 mg/mL, and a 50 mg vial in 25 mL gives 2 mg/mL. Check the vial capacity before adding solvent.

Most in-vitro protocols reconstitute at 1 to 3 mg/mL in sterile bacteriostatic water. Swirl gently rather than shaking. Reconstituted material is typically stable for up to about eight weeks under refrigeration. Keep lyophilized powder at -20°C for long-term storage.

Pre-mixed research blends of cagrilintide and semaglutide are available in 5 mg, 10 mg and 20 mg vials. Amylin-pathway and GLP-1-pathway combinations are an active area of metabolic research.

Prices are per 10-vial pack of one size. Email us to arrange a smaller order at the same per-vial price. Orders of $1,000 or more ship free, and delivery is typically about 10 to 15 days, duties paid.
