Exenatide
GLP-1 agonist
The first approved GLP-1 mimetic—derived from Gila monster saliva peptide exendin-4.
Exenatide was isolated from the Gila monster and modified for human use. It lowers blood glucose and modestly reduces weight. Largely replaced by newer GLP-1 drugs but remains a reference point for the peptide drug class…
Semaglutide
GLP-1 agonist
A GLP-1 receptor agonist peptide drug approved for type 2 diabetes and chronic weight management.
Semaglutide mimics glucagon-like peptide-1, slowing gastric emptying and increasing satiety. Weekly injection versions (Ozempic, Wegovy) produce significant weight loss in trials. It is a prescription drug—not a supple…

Are Exenatide and Semaglutide the same peptide?
No. They are different molecules with distinct names on labels and in research databases. Always match the full INCI or drug name—not a nickname on the front of the package.
Can I buy Exenatide or Semaglutide over the counter?
Prescription peptide drugs require a clinician and regulated pharmacy supply—they are not cosmetic INCI ingredients or bulk research powders sold like supplements.
