Description
GLP-1 S 2mg from Evolve Peptides is 2mg of GLP-1 S (semaglutide) in a sealed glass vial. GLP-1 S is a GLP-1 receptor agonist. It’s sold for laboratory research only.
What is GLP-1 S (semaglutide)?
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.

Reconstituting GLP-1 S 2mg
Concentration is just the amount in the vial divided by the water you add. With 2mg in this vial:
- 1ml of bacteriostatic water gives 2mg/ml
- 2ml of bacteriostatic water gives 1mg/ml
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.
Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake.
How to store GLP-1 S 2mg
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.
