What Is Semaglutide? The GLP-1 Agonist Explained
Semaglutide is a GLP-1 receptor agonist and the active ingredient in Ozempic and Wegovy. Here is what it is and what to check on a research COA.
Semaglutide is a GLP-1 (glucagon-like peptide-1) receptor agonist. It is the active ingredient in the FDA-approved medications Ozempic and Wegovy, which sets it apart from most compounds sold in the research peptide market.
Regulatory status
Semaglutide is a 31-amino-acid GLP-1 analog with a fatty-acid side chain. As a prescription drug it is approved under the Ozempic and Wegovy brands; this page does not summarise its effects or uses. The research-market version is sold as a powder for laboratory research, not as the regulated medication.
Approved medication versus research powder
The pharmaceutical products (Ozempic, Wegovy) are tightly regulated and quality-controlled. A research-market Semaglutide powder is a different product entirely, and its quality depends on the vendor and its COA. Do not assume equivalence to the pharmaceutical product.
What to check on a Semaglutide COA
Because GLP-1 peptides are in high demand and frequently counterfeited, COA scrutiny matters. Confirm a named lab, mass-spec identity, HPLC purity with decimals, a matching batch, a recent date, and endotoxin and sterility testing for injectable research preparations.
Frequently Asked Questions
Is research Semaglutide the same as Ozempic?
No. Ozempic and Wegovy are regulated pharmaceutical products. Research-market Semaglutide powder is a separate, unregulated product whose quality depends entirely on the vendor and its COA. Nothing here is medical advice.
Why is COA scrutiny especially important for Semaglutide?
High demand for GLP-1 peptides makes them a frequent target for counterfeiting and mislabeling, so independent identity and purity verification matters more, not less.
What should a Semaglutide COA include?
A named lab, mass-spec identity, HPLC purity with decimals, a matching batch, a recent date, and ideally endotoxin and sterility testing.
