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…
Retatrutide
GLP-1 agonist
A once-weekly GLP-1/GIP/glucagon receptor triple agonist in late-stage trials for obesity—next-gen metabolic peptide drug.
Retatrutide activates three incretin-related pathways, producing large weight loss in phase 2 trials (SURMOUNT-1 and related studies). It is not yet widely approved like semaglutide or tirzepatide. Prescription-only when…

Common questions
What is the difference between Exenatide and Retatrutide?
Both are categorized under GLP-1 agonist in our directory—here is how they differ in name, use, and label context. Exenatide is categorized as GLP-1 agonist; Retatrutide as GLP-1 agonist. Exenatide: The first approved GLP-1 mimetic—derived from Gila monster saliva peptide exendin-4. Retatrutide: A once-weekly GLP-1/GIP/glucagon receptor triple agonist in late-stage trials for obesity—next-gen metabolic peptide drug.
Are Exenatide and Retatrutide 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 Retatrutide 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.
