GLP-1 S (semaglutide) at a glance
Semaglutide is a GLP-1 receptor agonist developed by Novo Nordisk. A fatty acid chain lets it bind albumin, which gives it a half-life of about a week.
It’s approved as Ozempic and Rybelsus for type 2 diabetes and as Wegovy for weight management.
GLP-1 S mechanism of action
GLP-1 is a gut hormone released after a meal. It tells the pancreas to release insulin, but only when blood sugar is high, and it slows how fast the stomach empties. Receptors in the hypothalamus pick it up too, which is where its effect on appetite comes from.
Natural GLP-1 is broken down by the enzyme DPP-4 within a couple of minutes. Semaglutide swaps one amino acid to resist DPP-4 and carries a fatty acid that binds albumin in the blood. Together those changes stretch its half-life to about a week, which is why it’s studied as a once-weekly compound.

How to reconstitute GLP-1 S 5mg
Concentration is just the amount in the vial divided by the water you add. With 5mg in this vial:
- 1ml of bacteriostatic water gives 5mg/ml
- 2ml of bacteriostatic water gives 2.5mg/ml
- 3ml of bacteriostatic water gives 1.67mg/ml
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.
Most labs use bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll it gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
Storage and shelf life
The dry powder keeps best cold: 2 to 8°C in the fridge, or -20°C for long-term storage. After reconstitution, store it in the fridge and finish it within roughly four weeks.

Common questions about GLP-1 S 5mg
How much is in the GLP-1 S 5mg vial?
5mg of lyophilized powder. The amount is printed on the label.
Can GLP-1 S be used in people or animals?
No. It’s sold for laboratory research only and isn’t approved for human or veterinary use.
Is it in stock?
Yes, GLP-1 S 5mg is in stock now.
Is GLP-1 S the same as semaglutide?
Yes. GLP-1 S is our product name for semaglutide research material, and the lab reports in the photos identify it as semaglutide.
Which size should I buy?
Pick by how much you’ll use. Bigger vials cost less per milligram, smaller ones mean less sits open in the fridge. The size comparison above lists every GLP-1 S option.
