GLP-1 S (Semaglutide): The GLP-1 Receptor Agonist in Metabolic Research
GLP-1 S (semaglutide) is a long-acting agonist of the glucagon-like peptide-1 (GLP-1) receptor — the single-target foundation of the incretin research class. It is one of the most-studied metabolic research peptides, and the reference point against which the dual and triple agonists are compared.
Everything below is provided for research context only. This is a laboratory research compound — not a medicine, and nothing here is medical or dosing advice.
What Is GLP-1 S (Semaglutide)?
Semaglutide is a GLP-1 analog engineered for a long duration of action: a fatty-acid diacid chain lets it bind albumin, slowing clearance and giving a once-weekly profile in research models. CAS 910463-68-2.
How It Works in Research
- GLP-1 receptor agonism: activates the GLP-1 receptor, driving glucose-dependent insulin secretion (insulin release scaled to glucose levels).
- Gastric emptying: slows gastric emptying in models.
- Satiety signaling: engages central appetite/satiety pathways.
These endpoints have been characterized in large randomized trials of semaglutide (glycemic and body-weight research), reported here as research context, not medical claims.
Where It Sits: Single vs. Dual vs. Triple
Semaglutide is the single-receptor agonist. Tirzepatide is a dual GIP/GLP-1 agonist, and retatrutide is a triple GLP-1/GIP/glucagon agonist. See the full GLP-1 receptor agonist overview for how they compare.
Handling in the Lab
- Ships as a lyophilized powder; reconstitute with bacteriostatic water using aseptic technique.
- Store the sealed powder cold and dark (long-term at -4°F); once reconstituted keep refrigerated at 36–46°F and use within a short window.
- Minimize freeze-thaw cycles and vial punctures.
- Judge quality by the lot-matched Certificate of Analysis (HPLC purity, mass-spec identity), not the label.
Frequently Asked Questions
What is GLP-1 S?
GLP-1 S is Golden State Bio's research-grade semaglutide — a long-acting GLP-1 receptor agonist studied in metabolic research. It is supplied for laboratory research use only.
How does semaglutide work?
It activates the GLP-1 receptor, promoting glucose-dependent insulin secretion, slowed gastric emptying, and satiety signaling in research models. These are research findings, not medical claims.
How is semaglutide different from tirzepatide and retatrutide?
Semaglutide is a single GLP-1 agonist; tirzepatide is a dual GIP/GLP-1 agonist; retatrutide is a triple GLP-1/GIP/glucagon agonist.
What is semaglutide's CAS number?
910463-68-2.
Is GLP-1 S approved for human use?
This product is supplied for laboratory research use only — not for human or veterinary use, and nothing here is medical advice.
