Description
Semaglutide for research, with the lab data on the page: each vial holds 5 mg of semaglutide as lyophilized powder in a glass vial. An independent lab confirms at least 99% purity by HPLC and mass spectrometry, and a Certificate of Analysis (COA) comes with every batch.
What is Semaglutide?
Semaglutide is a GLP-1 receptor agonist, a 31 amino acid analog of human glucagon-like peptide-1. Two changes set it apart from the natural hormone. An Aib residue at position 8 shields it from the enzyme DPP-4, and a C18 fatty acid chain on lysine 26 lets it bind to albumin. Native GLP-1 is broken down within minutes, while semaglutide has a half-life of about a week, which made it a reference compound in incretin research.
- Glucose and insulin: glucose-dependent insulin release and glucagon suppression in cell and animal models.
- Gut and brain signaling: gastric emptying and appetite pathways in the hypothalamus and brainstem.
- Beyond metabolism: cardiovascular, kidney and neuroinflammation research.
Findings from cell and animal studies cannot be applied directly to humans. For the wider picture, read our overview of GLP-1 and metabolic research peptides.
Semaglutide, Tirzepatide or Retatrutide?
All three come out of incretin research, but they act on different receptors. Semaglutide works on the GLP-1 receptor only. Tirzepatide adds the GIP receptor, and Retatrutide acts on the GLP-1, GIP and glucagon receptors. That makes semaglutide the usual single-receptor reference when dual and triple agonists are studied.
Buy Semaglutide: quality, storage and shipping
Every batch is made in a controlled cleanroom. Mass spectrometry confirms the identity of the peptide and HPLC confirms its purity. Our guide on how to read a peptide COA explains what each value on the certificate means.
Store the powder at 2 to 8 °C and away from light, and keep any reconstituted solution in the fridge. For dissolving the powder in the lab we carry bacteriostatic water. Orders ship discreetly with tracking across the EU, and you can pay by card, Google Pay or crypto.
Questions about Semaglutide
How is semaglutide different from native GLP-1?
Native GLP-1 is cut by DPP-4 and cleared within minutes. Semaglutide resists that enzyme and binds albumin, so it stays active far longer.
What is the molecular weight of semaglutide?
About 4113.6 g/mol, with the molecular formula C187H291N45O59.

Semaglutide: common questions
Is Semaglutide lab tested?
Yes. Every batch of Semaglutide targets at least 99% purity, checked by HPLC and mass spectrometry.
What sizes does Semaglutide come in and what do they cost?
Semaglutide comes in these sizes, with prices in euro: 5mg for €39.99.
Is there a discount for buying more Semaglutide?
Yes. The discount applies in the cart: 3 items take 5% off, 6 items take 10% off and 8 items take 15% off.
How fast does Semaglutide ship?
We dispatch within 1 to 3 business days, tracked and in discreet packaging. Delivery usually takes 3 to 10 business days within the EU.
How should I store Semaglutide?
Keep the sealed vial cool, dry and away from light. For long-term stability, refrigerate or freeze it.
Is Semaglutide for human use?
No. Semaglutide is for research use only, not for human or animal consumption, and sales are restricted to adults 18 and over.
