What is semaglutide?
Semaglutide is a peptide. A peptide is a very small protein, made of amino acids joined in a chain.
It is known as a GLP-1 receptor agonist. GLP-1 is short for glucagon-like peptide-1, a natural gut hormone. A receptor is a docking spot on a cell. An agonist is a molecule that switches that docking spot on.
So semaglutide binds the GLP-1 receptor and turns it on. That is its chemistry in one line.
It ships as a dry white powder in a sealed vial. A vial is a small glass bottle with a rubber top. A lab must reconstitute the powder first, which means mixing it with liquid.
How researchers use semaglutide
- Receptor binding. Labs measure how strongly it holds the GLP-1 receptor.
- Signal studies. Studies track the chemical signals a cell sends once that receptor is switched on.
- Metabolic research. It is one of the most studied compounds in this field.
- Compound comparisons. Studies line it up against tirzepatide, which binds two receptors instead of one.
- Dosage response. Lab work compares small mg and mcg amounts. One mg is 1000 mcg.
- Stability. Labs check how long the mixed liquid holds up when kept cold.
What we stock
Our vials sit in the semaglutide category. Each one is quality tested for purity.
Labs often compare it with tirzepatide, which acts on two receptors. Both sit inside our wider research peptide range.
You will need mixing supplies as well. We sell bacteriostatic water and needles and syringes. Or see the full store.
Shipping in Canada

Orders go out with Canada Post or Federal Express. Tracking comes with every order. Orders over $399 CAD ship free.
Every box is plain and unmarked. The label does not say what is inside. You can pay by Interac e-Transfer at checkout.
Common questions
What does GLP-1 stand for?
It stands for glucagon-like peptide-1. That is a hormone the gut makes on its own.
How is semaglutide different from tirzepatide?
Semaglutide acts on the GLP-1 receptor only. Tirzepatide acts on GLP-1 and GIP receptors.
How do labs mix the powder?
They add bacteriostatic water to the sealed vial with a syringe. The powder then goes into solution.
How should a vial be stored?
Keep the sealed vial cool and out of sunlight. Once mixed, keep it in a fridge.
Is the packaging plain?
Yes. Every order ships in an unmarked box with tracking.
